About The Lock: We created the Boltlock and released it at the Brooklyn Museum to celebrate their David Bowie exhibit. It wasn't a coincidence. Sizewise the lock is in between a Babylock and a Medium Lock. This 14k gold Boltlock measures 3cm x 10mm. Can be machine engraved.

About The Chain: You might’ve noticed that the Not So Heavy Curb Chain is actually --finally-- a true "medium" curb chain. We heard you. Like our other curb chains, it has an old style Victorian feel because we oxidize the silver to give it that patina--and it's sturdy in a true "medium" sort of way. Sterling Silver Chain with 14k gold loops. The chain is about 2.7mm wide.
