Layer your favorite necklaces by attaching them to our Toggle Cari Clasp™ to create a single layered necklace that you can take on and off with ease, and is less likely to twist and tangle. This clasp connects multiple chains into a single necklace to create layered looks that can be taken apart and rearranged. The new improved design allows you to use any chain and it's existing clasp. Simply clasp each chain to the Cari Clasp™. You'll LOVE this invention!
