Duraflame fatwood are real wood firestarters that come from the tree stumps of non-endangered pines that continue to absorb quick-burning pitch after the trees have been felled. The concentrated, 100% natural resin ignites quickly from one match and generates an intense, sustained flame for lighting wood fires and charcoal. No new trees are cut down and no additives have been applied to the product. Duraflame fatwood is both user and environment friendly.
