Tritium Glowing Keychain (10-Year Green Glow)

Besides being somewhat dim, most keychain lights have batteries that only last a couple months before needing to be replaced—which often never happens since nobody has watch batteries lying around. But what if you could have this Mini Tritium Keychain, which lasts about 10 years without needing to be replaced? Now you can.
