What does it mean to hold the keys to hell? When you use the Gate of Hades Key Amulet, you can unlock your own hidden power and stores of knowledge to help you reach your full potential. The Gate of Hades Key naturally opens the gates to the Underworld, but also serves as a symbol of authority, truth, justice and freedom, and the mysteries that can never be solved (and perhaps shouldn’t be). Dimensions: 33 mm x 17 mm x 4.5 mm Brand new, amulet only.
