| Rose Scented Backflow Incense Cones Pack of 24 . Backflow incense cones send incense smoke downwards and are specifically designed to be used with backflow burners. This is because our backflow cones have an opening underneath the base thereby conducting the smoke downward. Depending on the burner you choose ie. mountain waterfall, the flow of smoke creates a liquid waterfall effect. Each pack contains 24 cones. Extraordinary scent. Long lasting. |
