It's the kid friendly polymer clay! Available in bright color kits, the Bake Shop range of polymer clays are easy for small and large hands to manipulate. They can be baked in a home oven to a plastic-like hardness while retaining their vivid coloring. Additional colors can be "mixed" by blending two colors together. Great for making jewelry, magnets, festive decorations and much more! Each block is non-toxic, lead-free. Includes: ten 1oz bars of colored clay and one 2oz bar each of black and white. A plastic modelling tool and complete instructions for modeling & baking are also included.
