Abstract: A closure bead provides a self-closing feature for closing the ends of stringing material. When jewelry is prepared, the closure bead may be used to close the ends of the stringing material after attaching the clasp, extension, jump ring, pendant, or the like. The closure bead may provide self-sealing closures that are designed to seal the ends of stringing elements, such as jewelry strands, ski ropes, climbing ropes, tool hangers, picture hangers, organizers, working ropes and the like. The closure bead may be used in various ways in various fields. For example, the device may be used in the medical field as a closure device, or in computers, electronics or children's toys as a way to seal wiring.
