The cones are crafted using the highest quality ingredients to offer a long lasting fragrance. There are 24 cones per pack with a burning time of approx 20 minutes per cone.
To use, place a backflow cone on top of your special backflow burner and watch as the smoke gently flows down and pools in the dish below.
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.
