Another popular choice, toggle clasps are an easy-to-fasten, secure way to finish a necklace or bracelet. Attach the toggle bar to one end of your jewelry and the toggle ring to the other. To fasten, simply pivot the bar so that it can slip inside the ring, then pivot the bar again to secure it. The bar is longer than the diameter of the ring to keep the clasp secured. Toggles are available for both single- or multi-strand designs.
