CosClay Professional Hybrid Plastic / Rubber Polymer Sculpting Clay ~ Stays Flexible & Shatterproof

These come in 1 lb / 453g boxes except for the Glow In The Dark which is 8oz / 226g.


Cosclay® is a specialized, hybrid, plastic/rubber polymer clay that will retain flexibility after curing.

Unlike other polymer clays, Cosclay®s’ unique flexibility imparts a durable and resilient quality that is suitable for endless applications.

This includes stop-motion characters, posable figures and much, much more! The possibilities are truly endless.

By incorporating durability and flexibility, Cosclay® will be able to withstand the rigors of heavy handling, mold-making and most importantly, the shipping of irreplaceable works of art from one location to another: especially during transit of great distances.

With Cosclay® that problem is now solved. Cosclay® is both shatterproof and damage resistant.

“Cosclay is an amazing new polymer clay that flex’s after it's cured.

We've never seen anything like it on the market. Our new Creature bust was sculpted in Cosclay and we love it!
