Crayola Terra Cotta Air Dry Clay 2.5 Pound Bucket Smoother, finer, and more moldable than traditional clay, Crayola Air Dry Clay softens with just a few drops of water. It is also well-suited for creating impressions, textures, and stamps. Kids can paint over entire slabs or add simple accents to create a colorful final piece of art. The clay also sticks to glitter, spangles, and other embellishments, so kids can bedazzle their sculptures however they want.
