This spool of Mandala Crafts colored jewelry wire is made from anodized aluminum. The wire will scratch if rubbing against hard surface. Please use a pair of rubber jaw or soft jaw pliers in beading, sculpting, or crafting process. This aluminum wire works well as flexible soft beading wires or strings for handmade jewelry making like wrapped crystal pendants, necklaces, bracelets, wire earrings, or wire wrapped rings. They can also be used in other crafts, such as making artistic wire sculpture or metal mesh.
