Wholesale Backflow Incense Burner is specially designed to create smoke that cascades downwards, pouring dramatically down the tower with a stunning effect that will catch your customer's eye. Once you have lit your incense cone, it will begin to smoke, the incense is heavier than air and it will fall dramatically in swirls and twists, through the hole and down over the item, to pool at the bottom. It is incredible to watch and very relaxing. Bring the essence of the mountains into your home with the Mountain Scape Backflow Incense Burner. This burner showcases an intricately carved mountain landscape, complete with cascading waterfalls and lush greenery. As the incense cone smolders, it produces a mesmerizing river of smoke that flows through the valleys, creating an atmosphere of peace and harmony. Please note: In order to create the smoke cascade effect you will need to use backflow incense cones.
