RICH IN RESIN - Fatwood is made from some of the most resin-rich pine trees in the world. This resin is what allows fatwood to burn so incredibly well! When burning, fatwood produces black smoke, but do not be alarmed as the burning resin makes the smoke black ECO FRIENDLY & ALL NATURAL - All Billy Buckskin Co. fatwood is eco-friendly. Made from dead tree stumps in the jungles of Mexico, fatwood is 100% natural and is not altered by any manmade chemicals! HOW TO USE - Simply place 2-3 sticks of fatwood in the center of your kindling, light one of the sticks and watch the fire start right before your eyes! Sometimes you will need to hold a match on one spot of fatwood for a couple of seconds to get the resin to flow and then light. Each piece is different so some may take longer than others.
