Aroma diffuser with multiple timer settings (1h, 3h, 6h) and multiple light color settings (red, white, blue, purple, green, etc). Lets out a soothing mist from the top. Plastic for water resistance and east cleaning, but with beautiful wood grain pattern. Set of six Rocky Mountain Essential Oils. Used, but most are almost totally full. Only the orange is half full. Super calming, relaxing, and soothing. Enjoyed for a few months but I was not consistent enough about using it, so am now sending the set off to a new home!
