Our reverse incense burners produce a mesmerizing downward flow of smoke. These seemingly magical devices make for a great conversation piece among friends and infuse your time spent at home with a calming, peaceful atmosphere. They also make a great gift for friends and family. Speaking of gifts, our cone incense burners come with a free gift of 10 special backflow incense cones so you can start relaxing right away. Please note that our backflow incense burners only work in windless environments. They don't work outside, under a fan, or anywhere with significant air flow - but they thrive in normal indoor environments!
