This is an aroma humidifier purchased from Francfranc. I've used it for several seasons, but I always cleaned it with citric acid before storing it. Operation has been confirmed. I cleaned it, but as you can see in the images, there is some minor soiling, but it doesn't affect its use. - Model name: PRIMA - Type: Aroma humidifier - Color: Silver - Power supply: AC adapter - Design: Petal-shaped Thank you for looking.
