Premo! Sculpey One Pound White...Sculpey Premo has a firm smooth texture. It is easy to knead and non-crumbling. Just like Sculpey III Premo works and feels like ceramic clay but will not dry out when exposed to air. Premo is exremely durable and colors will not bleed or smear- they will hold their "edges" while working on millefiore projects. Shape it into your desired form and bake according to package instruction (typically 275 degrees Fahrenheit for 30 minutes for every 1/4 inch of thickness). Once cool it can be sanded drilled carved and painted with water based acrylics. Ideal for artists of all ages. Non-toxic.
