The essential kindling for survival situations, Survive Outdoors Longer® All-Weather Fire Cubes™ are professional grade, all-weather fire starters that ignite easily and are designed to stay lit even in the worst conditions. Completely waterproof and windproof, each of these fire starter cubes will burn for 10-12 minutes, providing plenty of time to start a fire in the rain or boil a pint of water using a portable stove! Individually wrapped for ease of travel, each cube weighs only 0.2 oz., making them a lightweight but lasting addition to your survival gear. Each cube can be cut into eight pieces that burn for 2-3 minutes, giving you enough time to start a small bundle of kindling for your fire. The cubes burn completely smokeless and odorless and are nontoxic, helping to reduce environmental impact, and come with a Survive Outdoors Longer Fire Lite™ sparker and fire starting instructions. To ignite, simply scrape a small pile of shavings on top of the fire cube and aim the sparks from the Survive Outdoors Longer Fire Lite™ sparker at the shavings.
