--Nice and slim, exactly what I was looking for. Holds all my cards--has a hidden zipper pocket inside and an outside zipper pocket.  Holds enough money on both sides.  Or checks on one side.  I don't carry a checkbook anymore just a few loose checks. There is no pen holder but you can slip a pen on in the middle fold.  7 1/2 "x 3 1/2" x 1/2". I Love it. And RFID!  A perfect buy
