small and well! Actually, I would not write any more, because that was exactly what it was about me. 2 card is unfortunately the optimum, otherwise the format is too big or too thick. That you can still take a little gel is nice but of course that goes up to 20, otherwise the tickets must be 2x folded. I also have a slightly larger with maps on the back, but I found the handy with maps on one side only advantageous because so can bend slightly and stretch the back and one can use a clear view gets a finger in the bill compartment.
