A structure that focuses on "foam" and "coldness". Vacuum insulation structure maintains drinking temperature. The drinking mug has a double-walled stainless steel structure, and there is a vacuum between the inside and outside of the body. Therefore, heat conduction to the outside air is suppressed, and both cold and hot drinks are kept at a drinkable temperature. There are protrusions on the bottom of the inner bottle to create convection and foam when beer is poured. The perfect size for 500ml beer cans.
