These cones are designed so smoke cascades down to enhance beauty of burner and perfume your home for a longer time.
Once you have lit your incense cone, it will begin to smoke, the incense is heavier than air and it will fall dramatically in swirls and twists, through the hole of the special back flow oil burner and down over the item, to pool at the bottom. It is incredible to watch and very relaxing.
These Goloka Nag Champa incense backflow cones come in a handy resealable tin.
There are 24 cones in each tin with a burning time of approx 20 minutes per cone.
