If the Can Stamp was around sooner, we would never have the wasteful problem of half full cans. Nor would we need to interfere in intelligent-drunken-conversation with the "which can is mine?" question.
Next time you’re at a party, claim your can. Use the the Can Stamp -- a handy, little plastic keychain, with statements such as "Mine," "In Use," "Drunk" or "1 More." The brains behind Can Stamp made this product straightforward enough for any stage of your booziness. Simply press the stamp across the top curve of the can and rock it back and forth until the words are imprinted. That's it. You have successfully and politely warded off slurpers and backwashers.
Save the beer for your next party -- at $7.95, consider this an investment.
