Backflow incense cones are semi-hollow with an open hole at the base, designed to align with a hole or channel in a BACKFLOW BURNER (available separately – will not work with a standard burner). After a couple of minutes of burning, the smoke will begin to flow downward in a flow, creating a stunning visual effect as it cascades over or through the burner. NOTE: It is normal for smoke to flow from the top for a couple of minutes until the burning section reaches the hollow area inside the cone.

These perfumed backflow incense cones are made in India by Bangalore company Sacred Tree, and are perfect for everyday burning. Each pack contains 14 backflow cones, each approx 3cm in height. Each cone will burn for approx 15 minutes.
