This RESIX is a combination between Resin and Starch clay
Resin clay is different from Polymer clay (Sculpey, Premo, etc)
From our test it is more flexible than other resin clay (and more expensive)
But you can make very thin flower bud and leaves (it's more realistic) without afraid of breaking because of their high elasticity and flexibility
Self life : 1 year (put in the refrigerator after opening the package.
