35x11mm. Vintaj essential! Great clasp for bracelets & necklaces. It opens easily to hook onto chain or beading wire, so you don't need a jump ring. And it is heavy duty enough to stay closed. Be creative and wire wrap beads to the clasp for a decorative look, also try suspending pendants from the hook! The Vintaj jewelry design above uses the Vintaj Eternity Garden Ring, Vintaj Brass Filigree Bead - Round 14mm, and Vintaj Flower Petal Bead Caps. It also shows the Vintaj Hook & Eye Clasp Set, and the Vintaj Fine Oval Chain.
