Learn how to customize your 30MS Mash Kyrielight figure with outfit changes, head swaps, and parts swaps. Discover compatible accessories and step-by-step tips.
The 30 Minutes Sisters (30MS) line is all about mixing, matching, and making a figure truly yours. If you own the Mash Kyrielight model, you already know how charming her default look is. But the real fun starts when you start swapping parts and outfits to create new versions of her.
In this guide, we'll walk you through practical steps to customize your 30MS Mash Kyrielight using compatible parts, including the 30 Minutes Sisters (30MS) Option Hair Style & Face Parts Set (Chiyoko Sonoda/Rinze Morino) for a fresh look. You'll learn how to change outfits, swap heads, and mix accessories—all without breaking anything.
Understanding the 30MS System: How Parts Swaps Work
The 30MS line is built on a simple peg-and-hole system. Most limbs, heads, and torso pieces attach with standard 3mm joints, making swaps straightforward. The Mash Kyrielight kit follows this standard, so you can use parts from other 30MS kits and option sets without modification.
Before you start, check the connection points. The neck peg, shoulder joints, and hip joints are universal across the line. This means you can attach heads, arms, and legs from other 30MS figures or option sets. For outfit changes, the torso and skirt armor are designed to be interchangeable, so you can create new silhouettes.
- Always warm the plastic slightly (with warm water or a hairdryer on low) if a joint feels tight. This reduces the risk of breaking pegs.
- Keep a small parts tray handy to organize screws and tiny pieces during swaps.
Step-by-Step: Changing the Outfit on Your 30MS Mash
To change Mash's outfit, start by removing the current skirt armor. Gently pull the front and back skirt pieces away from the hip joint. They should pop off with a little pressure. Next, detach the torso from the hip by pulling apart at the waist joint. This reveals the chest and shoulder assembly.
Now you can attach a different torso or chest piece from another 30MS kit. For example, you could use a torso from a different 30MS sister to give Mash a new look. Slide the new torso onto the hip joint, then reattach the skirt armor. Make sure everything clicks into place securely.
If you want a more dramatic change, swap the arms and legs too. Pull the arms straight out from the shoulder joints and the legs from the hip joints. Attach the new limbs by pushing them in firmly. The 3mm joints ensure a snug fit.
- When swapping torsos, check that the neck peg aligns with the head joint—some torsos have slightly different neck positions.
- Use a soft cloth to grip parts when pulling—this avoids scratching the plastic.
Head Swaps and Face Customization
Changing Mash's head is one of the easiest ways to personalize her. The head attaches via a ball joint at the neck. To remove it, gently pull the head upward while holding the neck. If it's tight, twist slightly while pulling.
You can then attach a different 30MS head, such as the one from the 30 Minutes Sisters (30MS) Option Hair Style & Face Parts Set (Chiyoko Sonoda/Rinze Morino). This set includes multiple hair styles and face plates, giving you many combinations. Simply push the new head onto the neck peg until it clicks.
Face plates are also interchangeable. Most 30MS heads have a front face plate that can be swapped. Use a small flathead screwdriver to gently pry the face plate off, then press the new one in. This allows you to change Mash's expression without changing the whole head.
- When swapping face plates, align the tabs at the bottom first, then press the top in—this prevents cracking.
- Store unused face plates in a small resealable bag to keep them safe.
Adding Accessories and Custom Details
Beyond parts swaps, you can enhance Mash with accessories from the 30MS line. Weapon sets, backpacks, and effect parts attach to the 3mm holes on her back, arms, or legs. For example, you can add a shield or a spear to give her a more battle-ready look.
If you're feeling creative, you can also use decals from other kits, such as the G-Rework Decal - MG ZGMF-X42S Destiny Gundam Use, to add unique markings. These decals are designed for Gundam kits but can be applied to 30MS parts with careful trimming. Just cut out the decal you want, soak it in water, and slide it onto the surface.

For a more permanent customization, consider painting. Use a primer designed for plastic, then apply your chosen colors. Masking tape helps create clean lines. Remember to let each coat dry fully before adding another.
- When applying decals, use a cotton swab to press out air bubbles.
- If you paint, use a clear topcoat to protect the finish.
Customizing your 30MS Mash Kyrielight is a rewarding process that lets you express your creativity. Whether you're swapping outfits, changing heads, or adding accessories, the 30MS system makes it easy. Start with simple parts swaps and gradually experiment with more advanced techniques. With a little practice, you'll have a unique Mash that stands out in your collection.
