Basic Knowledge of Part Exchange

Part exchange for Nendoroids is a customization method that anyone with multiple figures can enjoy. Basically, most parts are compatible, allowing you to combine parts from different characters.

Before starting part exchange, it’s important to understand which parts can be exchanged and what charms they have. Having the correct knowledge will help prevent damage to the parts and allow you to enjoy customization safely.

Types of Parts That Can Be Exchanged

The main parts that can be exchanged with Nendoroids are 6 types. Facial expression parts are face plates that allow you to enjoy different expressions such as smiling, crying, and angry faces. Hair parts are divided into front and back hair, significantly changing the character's impression.

Hand parts can be exchanged according to poses and items held, with various variations such as gripping hands, open hands, and pointing fingers. Foot parts correspond to standing and sitting poses, while Body parts can express differences in costumes. Additionally, Accessory parts such as hats, glasses, and weapons can also be exchanged.

Since all parts are basically compatible, you can create your own original combinations.

Attractions and Benefits of Part Exchange

The greatest attraction of part exchange is the freedom to create original combinations. You can combine the expression of your favorite character with the costume of another character or change expressions and accessories according to the situation.

Moreover, a high cost performance is also a significant benefit. You can enjoy numerous variations just by combining the parts you already have without purchasing new Nendoroids. When taking photos, part exchange allows you to create various scenes, fully unleashing your creativity.

Furthermore, part exchange can lead to interactions with collectors who share the same hobby, serving as a trigger for sharing on social media and participating in communities.

Things to Check Before Exchanging

Before starting part exchange, there are several points to check. First, check compatibility. Generally, part exchange is possible with all Nendoroids, but there may be slight size differences between old and new models.

Next, perform a condition check of the parts. Check for cracks or deterioration in the joint areas and ensure they are in a condition that can withstand force without damage. Be especially cautious with used parts or those that have been stored for a long time, as the plastic may have hardened.

Finally, prepare your work environment. Set up a clean and soft cloth-covered workspace and keep small parts organized to avoid losing them.

How to Exchange Facial Expression Parts

Exchanging facial expression parts is the most fundamental aspect of Nendoroid customization. Just changing the face plate can significantly alter the character's atmosphere, making it the most frequently performed exchange task.

Facial expression parts are attached to the neck joint and used in combination with the front hair parts. By following the correct procedures and precautions, even beginners can exchange them safely. However, since the neck joint is a fragile part, careful handling is required.

How to Remove Facial Expression Parts

When removing the expression parts, start by removing the bangs part. The bangs part is usually secured with clips, so it can be easily removed by gently pulling. Applying too much force can cause damage, so if you feel resistance, do not force it and try from a different angle.

After removing the bangs, pull the expression parts out from the neck joint. At this time, hold both sides of the faceplate evenly and pull straight up. Pulling on only one side can risk bending or breaking the neck joint.

If it is hard and difficult to remove, lightly warm it with a hairdryer or soak it in lukewarm water for a few seconds to make it easier to detach. Especially in winter or low-temperature environments, the plastic can become hard, so it is recommended to warm it up before working.

How to Attach Expression Parts

When attaching new expression parts, check the orientation of the neck joint before installation. The neck joint has a front and back, and if it is not inserted in the correct orientation, it will not be secured properly. Look closely at the shape of the joint and match it with the shape of the hole in the faceplate.

When inserting the faceplate into the neck joint, make sure to push both sides evenly. If you push firmly until you hear a "click" sound, the installation is complete. If it is only partially attached, it may come off later.

Finally, attach the bangs part. Align the clip part of the bangs with the groove of the faceplate and push it in until you hear a click. It is reassuring to gently shake it to confirm that it is securely fixed.

Precautions for Changing Expression Parts

The most important thing to be careful about when changing expression parts is the risk of damaging the neck joint. The neck joint is thin and prone to breaking, so never pull it with excessive force. Especially if the same expression parts have been attached for a long time, the plastic may stick together and become difficult to remove.

Also, be careful of paint chipping. The faceplate and neck joint may rub against each other, which can cause the paint to chip. If you frequently change parts, applying a thin layer of baby powder to the rubbing areas can improve sliding and prevent paint chipping.

Temperature management is also an important point. In low temperatures during winter, the plastic becomes hard and the risk of damage increases, so always warm it up before working. Conversely, in high temperatures during summer, it may become too soft and risk deformation, so it is ideal to work in a cool place with air conditioning.

Compatibility of Expression Parts

Nendoroid expression parts are generally compatible across all products. From the early Nendoroids to the latest releases, they use the same neck joint specifications, allowing for expression exchanges between different characters.

However, there may be slight differences in neck joint sizes between old and new models. Particularly around the 300 series, there were specification changes, so attaching an old faceplate to a new neck joint may feel a bit loose. Conversely, attaching a new faceplate to an old neck joint may feel tight.

If there are compatibility issues, you can resolve them by adjusting with putty or thin tape. However, forcing the attachment can cause damage, so if it feels too tight, it is recommended to warm it up or try a different combination.

How to Change Hair Parts

Changing hair parts is a fun customization that can dramatically change the character's impression. Since the bangs and back hair parts can be exchanged separately, the combinations are endless.

However, hair parts are not as compatible as expression parts, and their shapes and sizes can vary greatly depending on the character. Therefore, it may require some trial and error to check compatibility by actually trying combinations.

How to Change Bangs Parts

The bangs part has a clip structure and is attached to the top of the faceplate. When removing it, hold both ends of the bangs part and gently pull it upwards. Applying too much force can damage the clip part, so work slowly and carefully.

When attaching a new bangs part, align the clip part with the groove of the faceplate. Once aligned in the correct position, press down from above until you hear a "click" sound. If it is not securely fixed, it may come off during display.

Depending on the bangs part, the size and shape may vary, so it may not fit perfectly on all faceplates. There may be gaps, or conversely, it may be too tight to attach, so it is recommended to check the shape before combining.

How to Replace the Back Hair Part

The back hair part is directly connected to the head part. When removing it, hold the base of the back hair part and pull it out from the head. If the connection part is tight, warming it with a hairdryer before working will make it easier to remove.

When attaching a new back hair part, align the insertion part with the connection hole of the head. Unlike the bangs part, it is not clip-type but insertion-type, so it is important to push it in firmly all the way. If it is only partially attached, it may come off during display.

Many back hair parts are heavy, so in the case of long hair or voluminous hairstyles, it can easily become unbalanced. Stability can be improved by securely fixing it with a base stand or using parts that support the back of the head.

Points to Note When Replacing Hair Parts

When replacing hair parts, it is important to pay attention to the compatibility of the bangs and back hair. The bangs and back hair of the same character are designed to be used together, so combining parts from different characters may result in gaps or interference.

Also, be aware of differences in hair size and volume. Combining bangs from a short-haired character with back hair from a long-haired character may result in an unbalanced appearance. Conversely, by successfully combining them, it is also possible to create interesting and surprising customizations.

Paint chipping on hair parts is another point to be careful about. Frequent attachment and detachment may cause the paint on the connection parts to chip. Especially for dark-colored hair parts, paint chipping is more noticeable, so handle them with care.

Compatibility and Selection of Hair Parts

Hair parts have limited compatibility compared to expression parts. While bangs parts can be used with many faceplates, back hair parts may not be attachable depending on the shape of the head. In particular, twin-tail or special hairstyle parts tend to have lower compatibility.

Finding a good combination requires trial and error. It is also a good idea to refer to examples of combinations from other collectors on social media and in communities. A popular combination is that simple short hair bangs parts are highly versatile and go well with various back hair.

Color combinations are also an important factor. Combining hair parts of similar colors will look natural, but intentionally combining different colors to create a two-tone hair effect can also result in a unique and interesting customization.

How to Replace Body Parts

Replacing body parts is an important customization that expands the variety of poses and outfits. By replacing hand parts, foot parts, and torso parts, various situations can be expressed.

Body parts have relatively high compatibility, and the risk of damage is not as high as with expression parts. However, since the joint parts can easily become loose, it is important to know the appropriate countermeasures.

How to Replace Hand Parts

Hand parts are connected to the arms via wrist joints. When removing, hold the wrist part and pull it straight out. It becomes easier to remove if you twist while pulling, but be careful not to apply too much force as it may damage the wrist joint.

When attaching new hand parts, check the direction of the joint before inserting. The wrist joint has a directional aspect, and if it is not attached in the correct orientation, the pose will look unnatural. Push it in firmly all the way and gently pull to confirm that it does not come off.

The hand parts are prone to loosening due to their high frequency of use. If they become loose and prone to falling off, you can resolve this by applying a thin layer of topcoat to the joint area or wrapping it with putty to adjust the thickness. Using official spare joints is also effective.

How to Replace Foot Parts

The foot parts are important parts that connect to the base to allow the figure to stand. When removing them, first detach them from the base, then pull out the ankle joint. The shapes of the foot parts for sitting poses and standing poses are different, so choose according to the pose.

After attaching the new foot parts, balance adjustment is necessary. Insert the foot part's support into the hole of the base and adjust the angle while checking the balance front to back and side to side. If the center of gravity is off, the figure is more likely to fall, so repeat fine adjustments until it stabilizes.

Compatibility with the base is also an important point. Official bases can generally be used with all Nendoroids, but if using a third-party base, check that the size of the foot part's support fits before use.

How to Replace Torso Parts

The torso parts have a structure that separates the upper and lower body and are connected at the waist. When changing outfits, it is common to replace the entire torso part. When removing it, hold the connection point between the upper and lower body and pull straight out.

Before attaching the new torso part, check the compatibility of the neck joint and foot parts. Depending on the torso part, the size of the neck joint connection hole may vary. Additionally, depending on the shape of the outfit, there may be poor compatibility with the foot parts, resulting in an unnatural appearance.

Changing Costume Parts is also included in torso replacement. If there are interchangeable costume parts, disassemble the torso before changing the outfit. Since there are many small parts, it is recommended to work while placing them in a small container to avoid losing them.

Compatibility of Body Parts

Body parts are generally compatible with all Nendoroids. The joint standards for hand parts, foot parts, and torso parts are unified, allowing for free combinations between different characters.

However, there are compatibility issues due to size and design. For example, combining the torso of a large character with the hands and feet of a small character may result in poor balance. Conversely, enjoying that imbalance is also part of the fun of customization.

Color combinations are also a point to consider. When exchanging parts between characters with different skin tones, the seams may become noticeable. It is necessary to either exchange parts between characters with the same skin tone or find ways to hide the seams with the outfit.

Differences and Compatibility Between Old and New Models

Nendoroids have different specifications depending on their release period, with significant changes occurring around the 300 mark. Understanding the differences between old and new models can help prevent issues during part exchanges.

In general, there is compatibility between old and new models, but the sizes and shapes of the joints may differ slightly, leading to differences in fit. Knowing this difference allows for appropriate handling.

How to Distinguish Between Old and New Models

The easiest way to distinguish between old and new models is to check the product number. Generally, it is said that specifications changed around the 300 mark. Items before that are considered old models, while those after are considered new models. However, there is no clear boundary, and changes were made gradually, so it is important to understand that there may be individual differences.

Differences in Packaging can also be a clue for identification. Old models often have outdated packaging designs, while new models typically have improved packaging. Additionally, there are differences in the content and presentation of the instruction manuals.

Directly checking the shape of the neck joint is also a reliable method. The neck joints of old models tend to be slightly thicker, while new models are generally a bit thinner. When you actually hold them and compare, you can feel the subtle size difference.

Part Compatibility Between Old and New Models

Between the old and new models, the expression parts are basically compatible. There are some size differences, but they can be attached. However, when attaching the old model's faceplate to the new model's neck joint, it may feel loose, and conversely, when attaching the new model's faceplate to the old model, it may feel tight.

The hair parts are also compatible, but since the sizes of the connection parts differ slightly, there will still be differences in the fit. In particular, the back hair parts have significant individual differences, with some fitting smoothly while others may feel quite tight.

Care should be taken as forcing the attachment can cause damage. If it is too tight to fit, warm it with a hairdryer to soften it before attaching. If it still doesn't fit, it is recommended to try a different combination instead of forcing it.

Troubleshooting Compatibility Issues

For parts that are loose, using putty is the simplest and most effective solution. By wrapping putty thinly around the neck joint or wrist joint, the parts can be securely fixed. There is also a method of applying topcoat to adjust the thickness.

For parts that are tight, warming them is the basic approach. Warming with a hairdryer for about 10 seconds or soaking in lukewarm water at around 40 degrees Celsius for a few seconds will soften the plastic, making it easier to attach. However, be careful not to overheat, as this can cause deformation; proceed while checking the condition in short intervals.

If it still doesn't resolve, it is important not to force it. If damaged, it can be difficult to repair, so it is recommended to try a different combination of parts or exchange them with the same type. Utilizing official spare parts is also a good method.

Compatibility with Other Products

Nendoroid figures have some compatibility with other deformed figures. By sharing parts with products that are similar in size, such as Nendoroid Dolls and Obitsu 11, the range of customization expands even further.

However, since the manufacturers and product lines are different, there is not complete compatibility. It is important to enjoy trial and error while understanding the characteristics of each product.

Compatibility with Nendoroid Dolls

Nendoroid Dolls are products that combine Nendoroid face parts with fabric costumes. The expression parts and hair parts are completely compatible, and can be freely exchanged between regular Nendoroids and Nendoroid Dolls. Since they use the same faceplate standard, there are no issues with attachment.

The body parts are basically not compatible. The body of the Nendoroid Doll is a jointed body, which is completely different in structure from a regular Nendoroid. Therefore, the torso and limbs cannot be directly exchanged.

However, costumes and accessories may be interchangeable. While it is difficult to dress a Nendoroid in a Nendoroid Doll's fabric costume, small items and accessories can be used if they fit in size.

Compatibility with Obitsu 11

Obitsu 11 is a ball-jointed doll with a height of about 11 cm. Since it is similar in size to Nendoroids, costumes and accessories are easy to interchange. In particular, costumes for Obitsu 11 can often be worn by Nendoroid Dolls, expanding the range of customization.

The body parts have a different structure, so there is no direct compatibility. While Obitsu 11 moves with ball joints, Nendoroids use a parts exchange system, resulting in fundamentally different connection methods. However, with some ingenuity, it is possible to combine them, and some collectors modify Nendoroid faces to fit on Obitsu 11 bodies.

Such modifications require skill and ingenuity. It may require processing with glue or putty, which can be challenging for beginners, so it is recommended to start with simple costume interchanges.

Compatibility with Other Figures

Compatibility with other deformed figures, such as Cu-Poche and Picconeemo, is limited. Each manufacturer uses its own standards, so direct part exchanges are generally not possible. The sizes also differ slightly, so even if you try to attach them, they often do not fit.

However, there are cases where small items and accessories can be shared. Small items such as weapons, hats, and glasses can be used across different product lines as long as they fit. Especially among products with similar scales, you may enjoy unexpected combinations.

It is important to have a mindset of enjoying experimentation. Even if there is no official compatibility, with some creativity, combinations can be made. There is joy in discovering your own customization while referring to examples from other collectors on social media and in communities.

Tips to Prevent Failures in Part Swapping

To safely enjoy part swapping, it is necessary to keep a few important points in mind. With proper preparation and the right techniques, the risk of damage can be significantly reduced.

Part joints, especially neck and wrist joints, are prone to damage, so careful work is required. By practicing the following tips, you can enjoy part swapping safely for a long time.

Prepare an Appropriate Working Environment

Before swapping parts, prepare a clean and organized workspace. Laying a soft cloth or mat on the table will help prevent damage if parts are dropped. Additionally, using a white cloth makes it easier to find small parts.

It is also important to have measures to prevent losing parts. Prepare small containers or trays to immediately place removed parts in. Especially hand parts and accessory parts are very small and can easily be lost during work. Using ziplock bags to manage them is also effective.

It is also important to ensure bright lighting. If the area is dark, it becomes difficult to work and can lead to applying excessive force. Use a desk lamp to ensure sufficient brightness and work in an environment where you can see the details clearly.

Do Not Apply Excessive Force

The most important thing in part swapping is to work slowly and carefully. Rushing can apply excessive force to the parts, leading to damage. Especially neck and wrist joints are thin and prone to breaking, so handle them with care.

If parts are stuck and won’t come off, warming them up is essential. Warming them with a hairdryer for about 10 to 15 seconds or soaking them in lukewarm water at around 40 degrees for a few seconds will soften the plastic, making it easier to remove. Prioritize warming them up rather than pulling them forcefully.

You also need to be careful about the direction you pull. Pulling at an angle can risk bending or breaking the joint. Always pull straight out with even force. Using both hands to apply equal force from both sides can reduce the risk of damage.

Manage the Temperature of the Parts

Extra caution is needed in winter. In low-temperature environments, plastic becomes hard and is more prone to damage than usual. It is recommended to warm them up with a hairdryer or work in a warm room before starting. When warming, do it for a short time of about 10 to 15 seconds while monitoring the situation.

In summer, be careful not to make them too soft. In high-temperature environments, plastic can become too soft and prone to deformation. Avoid working in direct sunlight or in places that get hot. Ideally, work in a cool room with air conditioning.

As a tip for warming, when using a hairdryer, keep it at least 15 cm away to avoid localized high temperatures that can cause deformation or paint peeling. When using lukewarm water, soaking for less than 5 seconds in water at around 40 degrees is sufficient.

How to Deal with Loss or Damage

If you lose a part, you can use the official spare parts sales service. On the Good Smile Company official website, you can purchase generic parts such as neck joints and bases. However, availability may vary depending on stock status.

Searching for parts on flea market apps or auctions is also an effective method. You may be able to obtain only the necessary parts from junk items or opened Nendoroids. However, be sure to check the condition and compatibility before purchasing.

If a part is damaged, it is important to not attempt to repair it forcibly. Even if you try to fix it with glue, the strength will not return, and there is a high possibility of it breaking again. It is recommended to purchase official spare parts or use alternative parts.

Ideas for Enjoying Part Swapping

Once you master the basics of part swapping, it's time to unleash your creativity and enjoy original customizations. From infinite combinations, you can create your own special Nendoroid.

Sharing on social media and interacting with the community to gain new ideas or showcase your creations is also one of the joys of part swapping.

Create Original Characters

For those who have multiple Nendoroids, you can create original characters by combining parts from different characters. For example, by combining A character's expression, B character's hair, and C character's outfit, a completely new character is born.

Popular combination examples include pairing a simple expression with flashy hairstyles or matching a uniform-style outfit with a casual hairstyle. Color combinations are also important; using similar colors creates a sense of unity, while using contrasting colors gives a unique impression.

Collecting elements from your favorite characters to create your ideal Nendoroid is also a fun method. Attempting to recreate original characters as Nendoroids is also popular among collectors.

Choosing Parts by Situation

Customizing for seasonal events is also a fun idea. For Christmas, use red or green outfit parts; for New Year, use traditional Japanese clothing parts; and for Halloween, use cosplay parts to create a seasonal display.

When recreating everyday scenes, combine smiling expression parts with casual outfits and relaxed poses for the arms and legs. Conversely, if you want to express a battle scene, choose serious expressions, weapon parts, and dynamic poses.

If you are planning to take photos, selecting parts that match the background and theme can result in more impressive pictures. Thinking of combinations with a narrative aspect is also a creative way to enjoy.
