Each box contains 12 packs, and each pack has 40 cones. With the backflow lavender cones from Hem you can relax. The scent of lavender is known for its soothing properties. Lavender smells floral and spicy at the same time. These backflow cones are especially suitable for an incense waterfall (backflow burner). How do backflow incense cones work? Backflow incense cones ensure that the smoke flows down an incense waterfall. There is a simple trick behind this. This is because a tunnel has been installed lengthwise in backflow cones. The air in this opening remains relatively cool. Because cool air descends instead of rises, the smoke from these cones flows downwards. This creates the special backflow effect. Because backflow cones are hollow inside and give off more smoke, they also burn up a bit faster. Backflow incense cones are placed at the top of a backflow burner.
