IRIS / PU LEATHER LAB
Love the gloss.
Learn the care.
A practical library for miniature costume collectors. Understand PU leather, dress seamless bodies gently and learn what to do when something changes.
START WITH THE MATERIAL
Beauty has layers.
Surface finish, a flexible coating and a supporting textile. Understanding how they work together makes every care decision clearer.
Read the introduction ↗THE READING ROOM
Eight essentials.
What is PU leather? ↗
A textile and a polymer, working together. Start with the material beneath the shine.
The layers behind the gloss ↗
Understand what supports the costume, and why pulling a surface can damage more than the surface.
How long does PU leather last? ↗
There is no universal countdown. Age, formulation, storage and handling all matter.
Store it beautifully ↗
Separate, support and ventilate. Let your costume rest between scenes.
Can you wash PU leather? ↗
Read the care instructions first. For a delicate miniature costume, less handling is often better.
Reduce colour transfer ↗
Stain-resistant is not stain-proof. Reduce contact stress and check your body between sessions.
Dress a seamless body gently ↗
Small movements, supported seams and the right amount of slip.
When a seamless body is stained ↗
Identify the mark and the material before you reach for a chemical.

Build a repeatable care routine
- Inspect and record: identify the body material and clothing backing; record time, temperature and humidity. The source’s 24-hour test can itself stain a body, so prefer approved spare material and stop at any change.
- Reduce contact: use compatible pale innerwear or lining. Film is temporary; avoid tight wrapping and trapped moisture, then remove it. Powder alone does not block dye.
- Undress and inspect: the source’s 1-3 hour shoot and 6-8 hour display intervals are inspection reminders, not safe limits. Store dark clothes separately and check weekly for shadows, colour changes and tackiness.
The Japanese original is unchanged. It mixes TPE and silicone terminology and describes a 10% BPO treatment lasting 24-72 hours. This differs from the separate 12-hour IRIS example; neither is a validated procedure for every body. Use oils, detergents, chemicals and powders only as approved for the specific body and clothing.
