First, remove the external cap from the bottle, and then, the internal protective cap. Place the external cap back and put the reeds in the bottle. The number of reed sticks should be selected based on the size and temperature of the room and the intensity of the fragrance. The smaller and warmer the room, the less reeds you should use. Liquid absorbs into the reeds and starts to diffuse the fragrance within 12–24 hours. We recommend that you turn the reeds occasionally. The home fragrance lasts up to 16 weeks.
