This thin wallet has a nifty coin pocket on the outside to feed the meters. The snap enclosure and rounded ends were added to make it easy to tuck into a purse or front or back pocket. You can carry it in the palm of your hand. It will hold as many as 25 plastic credit and ID cards, plus folding money. The Taxicat wallet measures just 4 5/8 inches by 3 1/8 inches in size. When it's closed, it's only a quarter inch thick.
