These long burn incense cones are made in India so have nice exotic fragrances. When they are burned, the smoke flows down the incense tower like a waterfall, creating an unusual and beautiful effect. Size of the single cone: height 3cm, diameter 1cm, weight 2g. Light the cone and it will begin to make smoke that is heavier than air and so it will fall dramatically in swirls and twists, down through the hole at the base to create a mesmerising effect and fill the room with a delicate fragrance. Use in one of our Back Flow Incense Burners to create a mesmerizing effect. These cones are only for use with Back Flow Incense Burners. Best value ever, to cone a phrase.
