Wire Protectors (also called Wire Guardians) mean no more wear on the wire where it connects to your clasps and rings. Sold in packs of 25 pieces. .021 Inner Diameter.
1) Thread a crimp bead onto your stringing material, followed by a Wire Protector. Guide the wire through one end-hole, around the back (making sure it lays in the channel), then back through the other end.
2) Hook the threaded Wire Protector onto a finding just as you would an open jump ring.
3) Slightly pinch the Wire Protector so that the two end-holes touch, then pull the end of the stringing material and insert it back through the crimp bead.
