Lavender Backflow Incense Cones
When a standard incense cone is lit, smoke flows in the upward direction as hot air is lighter than room-temperature air. However, smoke travels through the hollow tunnel with backflow cones and cools down as it travels the hollow path. After it cools, it becomes denser and exits from the bottom of the cone and in the downward direction. This creates a 'waterfall' effect with the smoke.
Quantity: 1 box (24 backflow incense cones only)
