I am selling this item, which is a 2023 model, because I only used it for about a week. The inside has a little bit of dirt, but otherwise, there are no noticeable scratches or stains, and it is still in good condition. I checked the operation before listing it. It was shipped in the box shown in the images, so the box has some dirt and damage. I will attach the shipping label to this box for shipping, so please be aware of this. - Model Name: mistone 600S - Humidification Capacity: 600ml/h - Timer Settings: 1H, 2H, 4H Thank you for looking.
