Although I haven't used it this year, I did put water in it once to check its operation. I dried it thoroughly afterward, but there may be a small amount of moisture remaining inside. This item has been used for a short period, and there are some areas where water stains can be seen. Therefore, please consider purchasing only if you understand that this is a used item. If you have any questions, please feel free to ask. 〈Purchase Date〉 February 2025 〈Usage Period〉 Approximately 2 weeks ・Original box and instruction manual included ・Aromatherapy function unused 【Product Description】 Heated Ultrasonic Humidifier Steam and Mist 4L White (Model No.: HD3040J0) ◆Size (Main unit) Width: 210mm / Depth: 210mm / Height: 350mm / Cord length: 1.2m ◆Capacity 4000ml ◆Weight 1,800g ◆Product Specifications Humidification Capacity (Strong Mode): 400mL/h
