Polymer clay is a type of hardenable modeling clay based on the polymer polyvinyl chloride (PVC). Due to its non-toxic, strong plasticity, and durability, Gionlion polymer clay beads are ideal for jewelry-making earrings, bracelets, necklaces, pendants, anklets, kid’s crafts, and other beading projects. A set of colorful beads and tools meets all your beaded requirement, never bothered by object-missing trouble.
