Specifications:

Size: about 7mm long, 5mm wide, 1.5mm thick, hole: 0.7mm. Package: 50 Pcs/bag. Material: 316 Stainless Steel, hardness and rust resistant; shiny polished and vacuum plating, not easy tarnish.

Usage: wire protectors are designed to protect wire against wear from clasps and other sharp-edged components.
Easy to Use: simply put your crimp on your Tiger tail first then feed your wire up one side of the guardian, then down the other side and back through your crimps. Pull your crimps up and squash as normal.
Protect Your Wire: wire guardians are the perfect finishing end for the use with Tiger Tail or other jewelry beading wire to prevent breakages occuring at the pressure point formed when doing the final crimping.
Horseshoe Design: similar to bullion or French wire with a rigid, pre-curved horseshoe shape to cradle and protect your bead cord from fraying.
