This is an ultra-minimalist wallet with 2 slim card slots on one side and 1 elastic pocket on the other side that can hold a few dollar bills. In between, there is some stiffener, but no internal pocket. There is no ID pocket or space for keys or coins. Size is 4" x 2.5" so it easily fits in any pocket. Great if you like going out without carrying much, but too minimalist for many people. Some of the colors look fun, but I got the boring black one.
