This wallet will probably be mostly what I wanted it to be, but be forewarned it does not have much capacity, and it is not made of sturdy material. The material seems flimsy and is paper-thin, which does not instill confidence in its longevity. It may prove me wrong, and go on to last several years. Or it could fall apart within six months.
In short, it's a good concept that appears to have been executed using shortcuts in materials.
