Using your Fallout Vault Security Keycard Replica is easy - just display it proudly in the provided stand! It's a collectible, so there's no actual use for accessing vault doors. When handling, be gentle to avoid scratching the enamel design. To keep it looking great, simply use a soft, dry cloth to wipe off any dust. Store it in a cool, dry place away from direct sunlight to prevent any color fading. And remember, with only 5,000 made worldwide, it's a truly special piece to own!
