Is there anything worse than being at a party and having someone steal your drink? Sure! Taking a long swigg on a can only to realise it isn't yours. But now you can avoid both situations with this keychain-sized stamp that lets you brand an aluminium can with a permanent message, leaving no debate as to its ownership.
The aptly named CanStamp features a set of raised letters spelling out messages like mine, in use, fuel, and 1 more. And branding your beverage is as easy as pressing that stamp -- and its message -- it into the ridge just below the top of an aluminium can. Admittedly debates over ownership could flare up if more than one person brings the $US8 CanStamp to a party, so you might want to skip this one until they come out with a version you can personalise with your name, or a more specific threat.
