Green Mountain Firewood Logs are made entirely of aromatic sawdust, shavings, and wood chips, compressed and extruded into a convenient size. They are easy to start, burn efficiently, and won’t spit or spark. They are the natural alternative to pre-packaged manufactured logs made with petroleum waxes and other harmful additives. They are not impregnated with harmful petroleum waxes, chemicals, or toxic binders. All-natural fatwood fire starters are included so your fire is simple to get started. Make sure to store in dry conditions.
