This Aroma diffuser is very beautiful. The Black shade gives it a unique look. An Aroma oil diffuser is an object that disperses essential oils into the air. The diffuser has an opening or space for a candle and a little bowl or tray for storing a tiny quantity of essential oil. Put a few drops of essential oil on top of it and a tea light kept in it and experience the beauty of light plus the soothing fragrance around! This aroma diffuser is usually less pricey than nebulizing diffusers, depending on the style and design, and does not require electricity or batteries.
