Clever Clasp™ makes quick work of tricky fasteners! Innovative converters attach easily to the existing clasps on any necklace or bracelet. To fasten, simply hold the two ends near each other and the powerful magnetic force closes the clasp. A simple twist of the built-in safety lock offers extra security like no other clasp can! Set includes 1 gold-tone and 1 silver-tone extender (ea. 3" L) plus 4 magnetic clasps (2 each of gold-tone and silver-tone).
