Magnetic Multi-Layer Necklace Clasp with Sliding Tube Connector to Prevent Tangling: Multi-layered jewelry shouldn't be too complicated. This multi-layer clasp prevents multiple necklaces from tangling when worn. Suitable for making multi-strand necklaces, bracelets, or other DIY jewelry. Easy to Use: This custom spacer clasp is itself a connector – simply pull the tube to open and then close it with a magnetic slider – each half has multiple links to which you can add bracelets or necklaces. Flexible and Fun Design: Compared to ordinary magnetic clasps, this necklace connector uses a sliding clasp design for added security. We pre-assemble the rings and lobster clasps before you receive these magnetic tube connectors, saving you a lot of time. Once the necklaces are connected, you can simultaneously take off and put on all multi-layered necklaces by sliding the tubes.
