Back flow Waterfall incense burner. Just place a back flow incense cone and watch it flow.

For best effect make sure there are not air currents around.

5" tall by 3 1/2" wide. It comes with an assortment of black flow incense cones.

Back flow incense cones are special and to be used only with back flow incense burners. The cones have a hole at the base that makes the smoke go downwards. When placed over the hole of a back flow incense burner, the smoke will follow whatever channel there is, and will flow down as a waterfall or whatever other shape the incense burner has, creating a beautiful effect.
