Sandalwood Natural Backflow Incense Cones

Cardboard box with 12 sandalwood-scented backflow incense cones. Backflow incense cones have a small opening in the bottom to allow for the smoke to flow downward into a corresponding opening in a backflow incense burner, which creates the beautiful waterfall effect. The composition is also slightly different from normal incense cones, backflow incense cones have more of a certain (natural) powder in them to create the smoke for the waterfall effect. This makes backflow incense cones unsuitable for normal incense burners. A cone lasts for about 15 minutes. 100% natural. Ingredients: natural frankincense incense resin, joss-bark powder, wood powder, guar gum, incense resin and essential oils.
