It is an aroma diffuser that uses Bernoulli's principle to turn pressurized essential oils into a fine mist with a diameter of 1.5~5 micrometers, which is most easily absorbed by the body. This product works without the addition of heat or water, so you can enjoy the original properties of essential oils as they are. Without altering the particles or adding unnecessary humidity to the surroundings, the pure aroma and action of the essential oil is effectively distributed over a wide area. How to use: Fill a glass reservoir with 15~20 drops of pure essential oil.
