Texture Spheres are unique clay tools cast by hand in the USA. The sphere shape gives you the ability to control the uniqueness of your design. They can be used as a stamp or rolled in stripe or in winding patterns to create a different look every time you use them. Being easy to use, texture spheres are great for kids and students. Texture Spheres are made of high-strength plaster, do not stick to clay, and are very durable.
