Only two components are used in If You Care 100% Biomass Firefighters: FSC wood and non-GMO vegetable oil. Just like that. Use these eco-friendly fire starting cubes for campfires and outdoor fire pits as well as fireplaces, BBQ grills, wood-burning stoves and ovens. Our firelighters are extremely stable, have a long shelf life, don't lose their intensity or dry out when left open, don't smell bad, are non-explosive and non-toxic, can be stored safely next to or with food, and are safe to use around plants, flora, and aquatic life.
