Thank you for viewing. Nitori Product Name: Easy Water Supply Aroma Humidifier HM01 NNWH Height: Approximately 24cm Width: Approximately 18.2cm Depth: Approximately 18.2cm Model Number: BRI-N-32119 Product Code: 8301633 For 6 tatami mats Regular retail price: 3,990 yen I purchased this last year and used it about twice. After that, I cleaned it and stored it because it became warmer. I received a new one from an acquaintance, so I am selling this one while it's still in good condition. I only used it as a humidifier and never used the aroma function. Instruction manual included. It has a few creases. No box. Will be wrapped in bubble wrap for shipping. How about using it to prevent colds and other illnesses?
