The fast-lighting charcoal from Swift-Lite is the finest charcoal tablet available. The charcoal tablets are made out of extremely fine charcoal and pressed to make a clean, non-crumbly, non-exploding tablet. rnrnSimply light a tablet with a lighter or match and the tablet will develop a long-lasting, intense and regular heat. They glow and remain hot consistently for around an hour and have no impact on smell of the incense. rnrnCharcoal tablets are great for for burning loose incense, herbs and powders. The tablets must be contained in a heat proof container or burned on a medium such as sand. 10 - 3 mm tablets per roll.
