The mini keychain lantern is one of those things that when you get it you will not remember how you lived with out it.

The super bright white led allows for a full spectrum of color as if it where day time in the complete dark, and the LED is sure to last at least 10,000 hours of use, just replace the batteries and your ready to go. The Awesome power of this high intensity bulb is visible over 1 mile away. At less then $1 a piece you can't afford not to have this unique and useful pocket light led key chain. Batteries included.
