※ Confirmed to be working! Green House Beer Server Stand Type Ultrasonic GH-BEERO-BK Used a few times, cleaned, and stored at home. I think it's in a clean condition with no noticeable scratches or stains. Please note that the warranty period has expired. I will send it with two AA batteries inserted. I was able to confirm that it starts up, but since it's been a while, I don't know how much longer they will last. I am looking forward to your purchase if you understand that this is a used item. Make your beer more premium. Stand-type beer server. The "Stand-type Beer Server" is a home beer server that allows you to easily create beer foam like in a beer hall at home using ultrasonic waves. You can put in your favorite canned beer and create fine, creamy foam with ultrasonic waves. The overall pressure system supports 330ml, 350ml, and 500ml canned beers, as well as bottled beer (small bottles). Like a draft beer server in a bar, you can switch between liquid and foam with the lever, so anyone can pour it to their preferred balance. Also, the refrigerant that surrounds the beer allows you to cool the beer that has been chilled in the refrigerator even further. There is no need to prepare gas, and it operates with two AA batteries. It doesn't matter what glass or mug you use, so you can enjoy your beer even more deliciously with your favorite glass or mug.
