Backflow Incense Holders are specially designed incense burners that have a reservoir to channel the smoke from the back-flow incense to dramatically pour down the incense tower like a gentle waterfall.

Backflow incense are specially designed cones that create a thicker smoke that cascades down from the cone rather than rising like traditional incense cones.
