I've been using cards like this for a long time but they were too small. 3 cards would fit perfectly, even four, but no more. With this wallet, I can still slip it in my front or back pocket and have that extra space I need. It has a slot for my driver's license, another slot above it, and another slot on the side. There are 3 card slots on the back, one on the back. Between each page there is a central place for money or whatever. There is also a small diagonal slit in front of the 3 slits. I use this for coupons or quick cash. This is the perfect place to keep something you don't want to forget. You see this every time you use your wallet. Each slot is lined with striped fabric and the quality of the leather is excellent. I am very happy with my purchase.
