It's polymer clay. It can be baked in oven and is pretty hard after that.

@@user-ru3og3bo6v thanks, it’s amazing, it’s easier than paper clay

@@salroesd1776 for everyone it's different, for some paper clay is easier because you can adjust it whenever you need and much easier, while polymer clay if one mistake done needs lots of sanding. But of course the best thing in polymer clay is that you dont need to paint it and of course it's harder than paper clay.
