Incense Cones( backflow)

Incense waterfall burners are a point of relaxation during meditation. You can use them for their aroma or as a concentration point while meditating. Cones burn for about 15 minutes, a perfect amount of time to challenge yourself with quiet contemplation.

The difference between incense cones and backflow cones?

Typical incense cones are made in a very similar way to incense without a core.
Backflow incense cones are unique in that their incense smoke flows downwards instead of upwards. These cones have a small hollow tunnel through 3/4 of the center of the cone, ending with a hole at the bottom.
