On the inside, there are six card slots on each side (in the light green print) and a bill slot behind each.
Also there are two pockets in the center, one zippered and one with a velcro flap (in the dark print).
I mentioned that I made this set by request from a friend but I have a similar set for myself. I change out my purse occasionally but I use the billfold daily and I love it. My billfold becomes a file cabinet holding receipts and all the cards one carries these days. This billfold actually organizes it all and holds up to all the use.
