Don't like people mistaking your can of drink for theirs instead? Stop all that madness. Now you can stamp what's yours with the CanStamp.

It will permanently brand an aluminum can with a permanent message. No more debate on who's can belongs to who. The stamp features a set of raised letters spelling out messages like "Mine", "In Use", and and more.
