The skinny connector necklace is made from silver. Choose your favorite Mini or Small Lock to close it, as there is no lock included. You can personalize this piece in many ways; choose your own chain, lock, add a pendant or connect multiple chains to make a necklace or wrap bracelet. We especially like to add a Lettre D’amour pendant to make it even more personal. 2mm thick. 42cm long. Sterling Silver.
