Our backflow incense burners combined with our backflow incense cones are one of the most amazing incense experience you'll see. They smell just as good as our classic incense sticks and incense cones but are breathtaking and amazing to watch. Our backflow incense produce a thick smoke that runs like water, cascading over the holder like a waterfall and collecting in a pool. Backflow Incense cones need to be used in conjunction with our Backflow Incense Holders. Take a look now and see the amazement for yourself.
