Post the costume or wig you want and shape it through conversation with creators who love cosplay too.
So everyone can keep expressing the characters they love, more freely.
Costumes, craft, and photos all carry the power to inspire someone else's next expression.
COSMA is where that passion keeps moving.
We connect people passing things on, searching, commissioning, and creating through the same love of cosplay.

Ojyouri Guide
'Oyuzuri' is a term used among Japanese cosplayers for selling or passing on costumes, wigs, and props to other cosplayers. Unlike regular clothing, cosplay costumes are made for specific characters, making it difficult for general marketplace apps or secondhand shops to properly value them.
COSMA is a specialized marketplace built for this cosplay trading culture. Search by series or character name to find used cosplay costumes that you'd never discover on general apps. Since both sellers and buyers are cosplayers, trades happen with a shared understanding of each costume's true value.
The launch COSMA fee is 12% (normally 15%), including Stripe processing and payout fees. COSMA helps you pass cherished costumes to the next cosplayer and supports your cosplay life with events, studio search, and galleries.
