Brynnlee 300ml Beer Mug

Keep your favourite beverage cold with the Beer o'clock frosty mug, a clever drinking gadget that does not dilute the drink and can be used whatever the weather! The frosty mug is a lightweight plastic tankard, filled with a protected layer of liquid. After a few hours in the freezer, the liquid freezes, creating a super cold, frosty cup. Then all that is left to do is sit back and pour in the beer!
