This is an unglazed pottery aroma stone without using fire or electricity. You can enjoy your favorite scent easily. It is suitable for scenting your surroundings, such as around your desk or bedside. Place the stone on the attached special plate and put 5 to 10 drops of essential oil directly to the dented part. The soaked essential oil gradually vaporises as the scent slowly spreads. Whenever you feel that the scent has weakened, add your favorite essential oil.
