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 underprivileged 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. After burning backflow cones it is normal for a light oily residue to appear on the oil burner, for this reason we recommend protecting any furniture it is placed upon suitably. The residue can be easily wiped off the burner with a damp cloth. Please exercise caution when burning incense.
