This product is a beer server that allows you to pour your favorite canned beer with creamy foam created by ultrasonic waves. It is compatible with 330ml (11.16us fl oz), 350ml (11.83us fl oz), and 500ml (16.91us fl oz) cans, and can switch between liquid and foam in the direction of the lever like a draft beer server.
In addition, the server has a built-in heat insulating material, which keeps the set canned beer cold for a long time. It measures W120 x D186 x H402mm and weighs 620g (21.87oz). It does not require any gas, and operates with two AA batteries.
The company also sells products such as the handy beer server "Kokuawa" that attaches directly to canned beer and the "Beer Former" that inserts directly into the poured beer to create foam. It seems to be easy to enjoy even for people who do not have the space to install a server or outdoors.
