This necklace is made from a reclaimed vintage brass skeleton key. I wire wrapped a few black/silver crystals onto the key itself to embellish it slightly, the key itself is 3 1/2 inches long. The chain is 33 inches long so it slips right over your head. The chain has sections of black/silver crystals and clear rock crystal between the reclaimed vintage brass cable chain. Unfortunately due to the unique nature of this key and other reclaimed vintage materials, this item is one of a kind.
