Thank you for viewing. I purchased this in 2018 and stored it in a dark place after using it for about six months. I think it's in good condition because I only used it about once a week. It has been cleaned and wiped with alcohol. Although I don't see any noticeable stains, there might be some that I missed. A key point is that this is the black power cord type, as opposed to the more common red ones. I can't confirm its operation because I don't have any powder at the moment, but I have confirmed that it powers on. It comes with the instruction manual (slightly torn). I threw away the original box. Please consider this item understanding that it is a used product.
