Large Cooling Beer Mug II

The large cooling beer mug II is a special mug with double walls filled with a non-toxic, fast-freezing transparent liquid. Before use, place the mug upside down in the freezer (so the liquid spreads throughout the entire mug) for 2 to 4 hours, where it quickly freezes into one solid block of ice. The frozen liquid keeps the mug cold for a long time and helps keep your beer chilled as well. During hot summer days, you can enjoy not only cold beer but also any other beverage without diluting it with ice cubes. The mug has a capacity of 600 ml and is made of acrylic.
