A hook and eye clasp is a popular jewelry clasp used to fasten fabric by attaching it at one end to a metal ring, then passing the jewelry through the ring and connecting it to itself. It is a basic closure mechanism with many variations. To wear a hook and eye clasp, extend it from one end of the jewelry and thread it through the metal ring. Then close the clasp, repeating in the other direction. You can use a sterling silver hook and eye clasp for necklaces, bracelets, anklets, and so on.
