Use these extension chains to add extra length to your necklace designs. A simple chain with a decorative shape finishes the end of the chain. These need attaching to a jump ring at the end of your necklace, so will require pliers and an appropriate jump ring or split ring to attach. Once fitted to your necklace or bracelet fasten at any point along the chain with the catch on the other end of the necklace/bracelet. If the extra length is not required the extension chain will hang delicately down the back of the wearer.
