This wallet does exactly what it promises to do (it's a pity that's so uncommon these days...).  It easily holds currency, receipts, drivers' license and insurance card, business cards and 9 other assorted cards perfectly.  By perfectly, I mean any single card is easy to remove and replace, and the rubberized coat prevents things from just falling out.  Where my other wallets create an ungainly inch-thick bulge in my pocket, this wallet is so slim (about 4 mm) I can't quite tell I'm sitting on it.  The exterior is a nicely stitched cowhide, so it also looks quite nice (nicer than the picture, really).  The internal rubber coating does make it smell a little rubbery, but it's not notable and is likely to diminish with time.  If it does keep my stuff from getting wet in the rain or on the ski slopes, it'll be worth it.  Only thing lacking for complete perfection would be RFID blocking material in the composition.
