Pair these copper hook ends with a loop end to quickly and cleanly add a hook-and-eye clasp to the ends of leather, ribbon, and other jewelry cord. Options include bright, shiny copper plating and antiqued (distressed) copper plating to fit the mood and hue of your artisan jewelry. To use, place a drop of glue on the end of your cord, slide on the center crimp, then flatten the center section with round-nose pliers. The brass core of these copper plated jewelry findings means they're slightly more durable than solid copper findings, since copper is a soft metal.
