This is a milk frother from Hario. I've used it a few times. Operation has been confirmed. Model number: CQT-45 Microwave safe, but not oven or direct flame safe. Requires 2 AA batteries for use. I'll include the batteries that were in it, so you should be able to use it for a while. Since it's battery-operated, you can use it at home or outdoors ¨̮⑅* There is no box or instruction manual. It will be packed and shipped with available materials. It has been stored at home for several years. Please consider this before purchasing.
