can stamp

 

Sometimes keeping track of your beer at a house party can be a real challenge. Put it down for thirty seconds and it’ll be in someone else’s hand while you pick up a warm, flat can that’s been sitting there for hours. Rather than gamble, might as well just stamp your can with a marking only you will have. Enter the Can Stamp! Before you open your can, then press the Can Stamp on upper, rounded section of the beer leaving a visible symbol for you to identify your drink with. This may not save your life, but it will save your beer and that’s almost as important!
