Fantasia Air-Flow Natural Hookah Charcoals are lit in the same way as other natural hookah charcoals with an electric stove top, grill, or Single Coil Burner. Once no black is showing, they’re ready to be placed on your hookah bowl. These hookah coals are not meant to be rotated or ashed off on the hookah bowl. The upside-down 'V' elevates the heat and allows for oxygen to flow through the coal. When ash is accumulated around the coal you do not need to remove the coal.
