Features:

Convenience: Hexamine fuel tablets can burn in the wind/rain and are specially designed for portable pocket stoves. Simply hold a small flame (from matches or lighter) to the fuel tablets and they will light almost immediately. 
Lightweight: These 12 fuel tablets weigh only 2.4 oz.
Smoke-Free Cooking: The Hexamine fuel tablets burn clean and don't give away your location with smoke. 
Long-Lasting: Each tablet will burn for approximately 10 minutes, giving you enough time to boil water and cook most survival foods with just a few tablets. 

NOTE: Fuel tabs may have an odor before using, this is normal. We suggest keeping inside a plastic ziplock bag if stored with other gear.
