BALMUDA K04A-BK Oven Range Made in 2019 [Simple Operation Check] Set to coffee, put water in a mug, and confirmed that the water heated up. Other settings switched displays accordingly, and the display sound worked. The interior has been cleaned, but some stains remain. This is a used item, so it may not be suitable for those who are sensitive to such things. I think it's clean for its age, but I don't know the frequency of use. There is no instruction manual or original box. Only the items in the images are included. No comments, instant purchase OK. To prevent trouble, I do not offer exclusive listings.
