Jeweler’s Clever Business Card Rolls Into a Ring Sizer

So guys don't have to ask

I have a pile of business cards on a tray in my office, and I'd be hard pressed to remember where I met the people whose names are on those cards if it weren't for some hastily scratched notes in the white space. ("Start-up owner, kept joking about Mad Men, didn't catch my Tupac reference.")

It's generally hard to make an impression on a piece of cardstock that's 3.5 by 2 inches, but German agency Jung von Matt definitely found a winner with its incredible business card for jewelry company Marrying—which, as the name suggests, specializes in engagement rings and wedding bands.

The card rolls up, becoming a handy tool to measure one's ring size. The idea is that men who are shopping for a ring can use the card at home to subtly check the size of a woman's current rings, saving them the rather obvious reveal of saying: "Hey baby, what's your ring size? What? No reason."

The agency effectively married (sorry) utility with good advertising, and I like it.
