* Metal: 14K Gold Filled - Yellow * Inside Dimension: .22 mm * Finish: Shiny * More Details: Bead Tip Our single-loop beading tips are crafted in 14Kt yellow gold filled jewelers' brass, and form a double cup around a central hole, with a flat open loop at one cup edge. When you're using silk beading thread or ultra-flexible jewelry wire, consider finishing the ends of your beaded, knotted strands with clamshell bead tips. Also known as Calottes, these findings help hide the knots tying your piece to jump rings or clasps. Simply knot your thread firmly, ease the thread through the central hole, crimp the loop around your jump ring, and fold the cups around the remaining thread and the end of the flat loop. Try a pack of our bead tips today, and give your knotted jewelry designs a clean, professional finish! Stamped 14K 1/20.
