This item came with the purchase of an espresso machine. It is a product of Bluematic Japan. Not for sale - Model: MMF-802 - Functions: Heating / Frothing This product can easily make hot and cold frothed milk by simply adding milk and pressing a button. I used it once and then stored it. It is in very clean condition. Before listing, I confirmed the rotation of the frother and that it heats up, with the machine empty. The box has no tears, but please note that there are minor scratches. Please understand that this is a used item that has been stored at home for a long time before purchasing.
