Authentic Gold tone Louis Vuitton padlock and key pendant necklace

Louis Vuitton padlock and key dangling from an 
Unbranded Brass Chain. The chain is 22” but I can shorten the length OR you can adjust the length to choker size about 16” by using the lobster clasp which is attached to the back near the hook and eye closure. The single key is attached to the lobster clasp when you don’t want it to hang from the padlock.
