Most homes have a pack of cards laying around for spontaneous poker nights (or drinking games). But I bet you don't have a pack laying around that looks this good. Gent Supply Co sell these awesome monochromatic cards that come in both white-on-white and black-on-black. They're certainly not the most practical, but I'd take them over a normal pack any day.
