AMERICAN ART CLAY-Friendly Plastic. This is a wonderful creation! It is so easy to use; soften in a container of hot water in a matter of minutes; cut or form and let cool. That is all there is to it. Make beads; frames; pendants; embellishments; buttons; and more using your hands; a knife or mold; the possibilities are virtually endless. Each piece measures 7x1-3/8x1/16in. Look for solids; combinations of two colors or multi-colored. Made in USA.
