Use Aromatherapy Backflow Incense to recharge your energy. These cones are designed such that smoke cascade down to enhance beauty of burner and perfume your home for a longer time. 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 of the special backflow oil burner and down over the item, to pool at the bottom. It is incredible to watch and very relaxing. For Backflow Incense holder see below.
