Swift Lite Charcoal -
Each tube contains 10 tablets of Swift-Lite Charcoal suitable for incense burning. To use, remove a tablet from the roll, place in a censer or heat-proof container. Light the edge of the tablet with a match or taper. The light will spread quickly across the surface of the tablet. Resins and wood powders can be placed on top of the burning tablet to release a fragrant smoke."Warning: When the tablet has been lit do not handle as it will cause a burn. Do not dispose of the ash remains in a waste paper bin as this may cause a fire. Do not hold the tablet in your hand when lighting or when burning." These are the warnings the manufacturer felt were necessary to include. May we just add, if you don't know this already, you probably don't need to be playing with matches. Please show common sense when using this product.
