MUJI Ultrasonic Aroma Diffuser (Large) with Humidifying Function Used for one season. I'm selling it because I haven't been using it. I cleaned the aroma diffuser after using it, but some fragrance remains. I've cleaned the entire unit, but there are still some hard water stains that couldn't be removed, and black discoloration on the gray ultrasonic vibration part (see photos). I've confirmed it works before listing, but it's a used item and has been inspected by a non-professional. Please refrain from purchasing if you are sensitive to these issues. The original box is not included, so I will wrap it in bubble wrap and ship it in a cardboard box. Everything in the photos is what you will receive. Please comment if you have any questions. Color: White Humidification Type: Ultrasonic Applicable Area: 8 tatami mats and up Tank Capacity: 1L to less than 2L Humidification Rate: Less than 300mL per hour
