【SUNTORY】Kami-Awa Server [Premium Malt's] I won this in a Premium Malt's campaign. By attaching the device's metal part to the side of the can's spout and pressing the gold button on the front while pouring the beer into a glass, you can pour canned beer with fine, delicious foam. You can easily enjoy delicious beer. I hadn't used it for a while and the batteries had died, but I put in new batteries and checked the operation, and it worked without any problems. It runs on two regular AAA batteries. Please note that batteries are not included. Type...Premium Malt's
