Black No. 01 Relax -  Reminiscent of a quiet forest grove, this scent is perfect for deep relaxation. Vetiver relieves tension, and cypress calms the mind. Notes of vetiver, cypress, hiba, and bergamot. 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. O Paper Incense also makes a unique gift for friends and family. Winner of the 2019 Good Design Award. 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.
