I am over here kicking myself in the forehead because I managed to order my business cards just a hair big and not I can't use my Kate Spade card case...which I bought in May for a bday gift and have had in it's pkg without ever using or opening since I got it...just waiting for my cards to come in. So...now I have a case I can't use, and no case for the beautiful letterpress cards I had made. I need your help finding a SQUARE case of some sort about 3x3 and flat if possible. I thought perhaps a nice "compact mirror" case or something but have yet to find something that would work. I am considering selling my Kate Spade one since I have zero use for it. Is eBay the best way to do that?
