Sculpey Premo Clay is a high strength, fine-detail modeling compound for more experienced artists and sculptors. It's soft enough to blend easily but firm enough to hold fine detail, making it good for advanced techniques like caning, mokume gane and mica shift (contains a high concentration of mica particles).
Premo will stay soft until baked in your home oven. Extra clay won't dry out or crumble over time, so it can be reused for later projects. Safe and non-toxic.
