All the incense we sell is plant based, however this Premium plant based brand from Stamford has a higher fragrance percentage giving a more intense long-lasting aroma when in use. 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 back flow oil burner and down over the item, to pool at the bottom. It is incredible to watch and very relaxing. KDMD Plant Based Backflow Incense Cones - Sweet Musk in White
