Do I need a special holder for these incense cones?

Yes, to achieve the cascading smoke effect, these cones must be used with a backflow incense burner. While they will still produce fragrance on a standard heat-resistant surface, the smoke will only flow downward if placed on a burner designed with the correct internal channels.

What makes backflow cones different from regular incense cones?

Backflow cones are manufactured with a small hollow tunnel running through the center. This design allows the smoke to cool as it travels downward, making it denser than the surrounding air so it can create the signature waterfall visual that regular incense cannot produce.

Can I use these cones in a room with a fan or open window?

For the best visual results, it is recommended to use backflow incense in a still, draft-free environment. Moving air from fans or open windows can disrupt the smoke flow and prevent it from gathering in the burner's pools and channels as intended.
