This is a nifty waterproof "peanut" capsule lighter. Great for your keychain, pocket, or pack. The lighter can survive a dunking thanks to the rubber o-ring and screw-on top. The fuel is just regular lighter fluid, so nothing needs to be held down for a continuous flame. Since it is tightly sealed, the fluid will not evaporate while not in use like a Zippo or other fluid lighter.

Convenient, useful, and waterproof. Makes a great gift and an excellent addition to any kit.
