Cool Mist Humidifier with LED color changing lights. Works great! Lights and mist can be used together or separately. Long-lasting before it needs a refill. Has auto shut-off. Approx 7" diameter & 880 ml capacity (large) Comes with 6-pack of Lagunamoon essential oils. 10ml bottles. I took pictures of each bottle (except Eucalyptus - I forgot) and marked a black line on each to show how much is left. The oils come with a comprehensive chart of what tons of different oils are good for.
