A step-by-step guide to swapping the 30MS Option Hair Style & Face Parts Set for Mamimi Tanaka and Sakuya Shirase, with checkpoints to avoid loose pegs and scratched faces.
Quick answer
Pop the current 30MS face plate and front hair piece off with a soft plastic pry tool, test-fit the new Mamimi Tanaka or Sakuya Shirase parts without forcing them, then press each piece in until it sits flush. Work over a tray so small pegs don't disappear.
Why this set is a swap, not a build
The 30MS Option Hair Style & Face Parts Set is a parts pack, not a full figure. It gives you alternate hair styles and face parts for Mamimi Tanaka and Sakuya Shirase, so the job is removal and refitting rather than snapping a new kit together. That changes your prep: you need a clean, well-lit workspace and a place to keep the original parts safe, not a full set of nippers and sanding sticks.
When to leave the parts on the runner
If you plan to paint or topcoat the hair, keep the pieces on the runner until you are ready to work. Loose hair parts are easy to lose and easy to scratch when they roll around a desk. If you are only swapping for display, cut them free first so you can test the fit without dragging the whole runner around the figure.
A note on compatibility
Bandai lists this set as designed for use with 30MS figures, and the included hair and face parts are tied to Mamimi Tanaka and Sakuya Shirase. The catalog does not list every 30MS body or head that will accept these pieces, so treat other combinations as a test-fit rather than a guaranteed swap. If a peg feels tight, stop and check alignment before adding pressure.
Step-by-step: swapping the 30MS hair and face parts
- Set up a tray and light: Place a shallow tray or folded cloth under the figure and aim a lamp at the head. Keep the original face plate and hair piece in the tray as you remove them. Common mistake: working over a bare desk, where a dropped face plate can pick up dust or vanish under furniture. If you wear gloves, use nitrile rather than cotton; cotton fibers catch on face plate edges.
- Remove the front hair piece first: Grip the front hair piece near its base, not at the tips, and pull straight away from the head. If it resists, slide a soft plastic pry tool into the seam and rock gently. Checkpoint: the piece should release with steady pressure, not a snap.
- Pop out the face plate: Press from behind the face plate or use the pry tool at the edge, working around the rim rather than prying at one point. Common mistake: pushing on the painted face, which can leave a mark. Keep your thumb on the back of the head, not the expression. If the face plate will not budge, check for a locking tab before adding force.
- Test-fit the new face plate before pressing: Line up the pegs with the sockets and seat the plate with light pressure only. Rock it slightly to feel whether the pegs are aligned. Checkpoint: if one side sits proud, lift it out and re-align rather than forcing the opposite side down.
- Fit the new hair style: Seat the front hair piece first, then check any rear or side sections that came with the set. Press at the base of the piece until it sits flush with the head. Common mistake: pressing on thin hair tips, which can bend or stress the plastic. Run a fingertip around the seam; a uniform gap means the piece is seated.
- Do a final expression check: Look at the figure from straight on and from the side. The face plate should sit even in the head, and the hair should not press on the face. If the hair touches the expression, reseat the face plate before adjusting the hair.
- Store the spare parts: Keep the unused face plates and hair pieces in a small zip bag labeled with the character names, away from direct sun. Common mistake: leaving spare face plates loose in a parts box where they rub against other plastic. Label the bag now; loose 30MS face plates are hard to identify later.
