Sculpey is one of the oldest names in polymer clay, going back to the late 1960s, and it is made in the United States.

A conditioner for stiff polymer clay, in the larger 2 oz jar. Knead in a small amount at a time and repeat until the clay reaches the consistency you want.

It carries no pigment, so it will not noticeably shift the color of what you are conditioning.

Which softener do you need? This one is the larger format for reviving stiff block clay. The 1 fl oz Clay Softener & Thinner is the bottle to reach for if you also need to thin Liquid Sculpey.
