If you're new to backflow incense, you'll be amazed by the stunning waterfall effect created by these ingenious cones. Instead of rising up like regular smoke in traditional incense, the smoke from your backflow incense cones cascades down the burner thanks to a small hole drilled in the bottom of the cones. While the outside of the cone burns, smoke is trapped inside where it cools until falling out of the hole. This is what creates the gentle waterfall effect. At The Hippie House, we stock backflow incense cones in all of your favourite aromas, such as nag champa, sandalwood, white sage and more!
