Agar Wood - One of the most traditional incense materials, Agar Wood eases stress while cleansing your space. An individually packaged HA KO leaf is the perfect introduction to this new form of incense, which was developed over the course of five years by one of Japan's oldest incense makers. Each leaf can be used as subtle potpourri, giving off fragrance for up to three months, or as incense that burns for approximately seven minutes while cleansing and deodorizing an area. 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.
