If you are on the lookout to gift something useful to your father, then the thinnest 20 card wallet is the best thing that you can gift to him. You can rest assured that this leather beauty will amaze him. Even though it appears so slim, it has the capability of storing up to 20 cards in its four pockets.
The total thickness of this wallet is just ½” when it is fully loaded with cards. The pockets are arranged in such a way that they eliminate the build up of thickness. At $79.95 apiece, they are a steal. I will not be surprised if you end up purchasing one for yourself as well.
