Hi guys, Ive seen this question asked before but the answer didnt get answered. sorry if the answer is somewhere I didnt see.
I have a guy wanting a wallet with slit pocket slots like shown below. I dont understand how they work. what keeps the top cards from sliding down too far. with stacked card slots, you can fix each layer so that the card slides down only how far you want it, but with a single layer, i dont see how that would work.
If someone can explain how that works i would appreciate it. i would hate to turn the guy down but i dont want to make something that is not functional.
