About The Lock: The Regular Lock measures 3cm x 1.5cm with a thickness of 4mm Closure is 6mm. Fits best on all stone or pearl necklaces, and a variety of our thicker chains and bracelets. Can be hand or machine engraved. Hand engraving is priced on a case by case basis. Sterling Silver.

About The Hard Hook: We created the Hard Hook bracelet to allow for the locks to be "converted" into a bangle bracelet. Works beautifully with the Regular Lock, Medium Lock, and Heartlock. Can even be worn with multiple locks. The bracelets all have a certain "springiness" to allow for multiple sizes of locks to be worn with it. Regular fits up to a size 7 wrist and Large fits up to an 8. Some people prefer to wear the larger size for a more "bangly" feeling. Sterling Silver.
