One of a kind! This authentic Gucci lock and key came from my mom's vintage Gucci suitcase from the 1980's There are two necklaces: Toggle necklace with lock 18" - 14K gold plated, nickel and lead free - this is an unbranded chain I bought to hang the lock (not made by Gucci) Fine necklace with key 16" - 12K gold filled - spring ring clasp reads 1/20 12KGF M8Co (Not made by Gucci) The lock itself measures .5" wide x 1" tall for scale. I will include a Gucci box, bag and bow that I came with a Gucci wallet that I purchased on the Gucci website.
