Backflow incense cones 10 backflow incense cones per box. Backflow Incense is specially designed to create smoke that cascades downwards with a waterfall effect. It can be used with any backflow burner. When the smoke flows downwards it creates a stunning effect that will not only catch your eye but offer a calming and relaxing effect. Allow the tip of the cone to burn for 3-5 minutes to allow the backflow effect to start. Check out our full collection of Incense And Smudging products.
