How to use: After lighting a piece of HA KO Paper Incense, blow out the flame and place the smoldering leaf on a felt burner mat (sold separately), which should itself be on a flat, non-flammable surface. Each leaf will burn for approximately 5 - 7 minutes. Do not allow to burn unsupervised. Avoid placing in drafty areas or near any flammable materials.  Note that direct sunlight can cause discoloration.
