Can you imagine handing one of these concrete business cards to Patrick Bateman? "This is a chiseled Cheltenham font set at a depth of .5mm into polished micro-pebble concrete." You would probably pull back a bleeding stump. Hand one to anyone else and the impression left will probably be more favorable.

Drawbacks to a concrete business card? Could you carry more than three of them in a coat pocket? Also, your target will not likely keep it in his or her wallet. Then again, it would be very difficult to throw something so singular into the wastebasket. Anyway, a very cool idea from French design agency Murmure. Ideal if your name is Moses. (limité)
