The Golden Key (as seen in Borderlands 2 and The Pre-Sequel as in-game icon) can now be used as a keychain. Be prepared for whenever you will run into a golden loot chest yourself and carry this with you. The key is available in gold plated stainless steel.
* Does not come with guarantees of legendary loot.
* If you do find a loot chest, be aware of the loot midgets.
