8mm 22kt Gold plated Copper Round Bead collection has been eCoated to protect each piece from interaction with the environment. To prolong the life of our beads, we recommend using warm, soapy water and a soft bristle brush to remove dirt or debris. Please notice the inter matching component pieces with beads in the same metal category or another metal category. We create charms, toggles, caps, and clasps to match our bead designs!
