It becomes a reed diffuser that can be used by inserting a stick into a bottle. The thick white (fort) glass bottle made in Japan uses a mechanical plug and has an inorganic presence. It comes in a luxurious sticker box and comes with red and white rubber, making it ideal as a gift (only this product uses natural essential oils and some synthetic fragrances to help spread the scent). [Fragrance lasts about 4-6 weeks] * Depending on the usage environment, the liquid may be sucked up quickly, but the scent is soaked into the reed stick, so the scent will last. *If you reduce the number of reed sticks, the diffusion of the scent will be weakened.
