I have not a clue where this came from. Â Possibly attached to a larger holiday gift or as a give away. Â When used, the LED emits a pretty bright blue, great for seeing the lock you’re trying to open with your keys. Â But I never got the concept of having this as your keychain and having to fumble with it as you’re trying to open your door. Â Plus, every cell phone has some kind of flashlight app, so I’m covered.
