Available in white, and five new bright colors, this smooth, air-hardening sculpting material is ideal for freehand modeling and creating realistic sculptures. No kiln or heat baking required for drying. Dries to an almost ceramic hard surface with minimal shrinkage during the drying process. Can be moistened while pliable to encourage piece to piece adhesion, smoothing and blending and to avoid cracking, colors can be blended together to create new colors or unique marbling effects.
