Do I need a special holder for these incense cones?

Yes, to achieve the downward smoke waterfall effect, these cones must be used with a backflow incense burner. While they can be lit on a standard heat-safe surface, the smoke will only cascade downward when placed over the hole of a backflow-compatible holder.
