These Goloka white sage 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. These incense cones can be used along with a backflow burner to create impressive smoke flow displays. Goloka have been creating quality incense for over 16 years and part of their proceeds are given to charitable causes that help to provide meals for underpriviledged children and providing vocational training and scholarships. Please note that it is normal for backflow cones to take up to 10 minutes to create a smoking/mist effect when used with a backflow burner.
