I purchased a humidifier at a Nitori store on December 21st, but it didn't suit my home, so I'm selling it. Retail price: 7990 yen I used it for about 2 hours a day from December 22nd until today, but I changed the water every day, so it's in very clean condition and ready to be sold. I threw away the instruction manual and box. Please see the last photo for the purchase history.
