This is Crayola Air-dry clay. It is intended to be a material to keep children busy attempting to make ham fisted art. It is cheap and non-toxic. It cleans up easily with water. The tub is really good at keeping it from drying out. The internet arts and crafts folks hate it. They hate it because it frustrates anyone attempting to use it as one would polymer clay. Because it's real clay, and the rules are different.
