These cute sprocket charms in bright glass enamel colors are handmade in the USA by C-Koop Beads. Choose from 16mm (small), 19mm (medium), and 26mm (large) sprocket gears for making jewelry and fine artisan crafts with a steampunk twist. Each charm starts with sturdy copper sheet that's cut with precision then torch-fired with the final enamel color. These accessories may have the enamel color on one side or both sides of the finding. As with all handmade items, the slight variations on these jewelry findings enhances their aesthetic appeal.
