Backflow incense flows downward over an incense burner, to create relaxation through both sight and smell.
This beautifully scented incense can be used in regular burners, but is designed with backflow burners in mind.
Cone incense holder should be placed in a windless environment, otherwise the waterfall effect will not happen.
Stay 30-40cm away from the incense burner and watch the smoke flow down from the back-flow incense.
