This sterling silver crimp bead is burr-free and consistently-sized to save you time and provide a secure finish without knots. Use it with tiger tail, Beadalon® or any other wire stringing material. Choose a crimp with an inside diameter that will accommodate at least two thicknesses of the cord/wire you will be using, and more if you will be working with double or triple strands. Manufactured to exacting quality standards in our solar-powered facility.
