This has been my new wallet and key holder for everyday use for the past week or two. It eliminates many current frustrations. This great minimal wallet measures 4.3 inches x 3 inches and is 0.6 inches thick. With the recommended six cards in the key compartment, the build quality is quite good with vegan leather and elastic straps. On the other hand, we have a key organizer that I've never seen in a thin wallet. But as soon as I did, I was sold, which is pretty logical as those are the two most important things to always have in your bag. The organizer is suitable for most key designs. the hatch is open. I'm pretty sure the keys will stay in place. So overall the minimalist wallet is pretty cool and I'm sure a lot of people will end up being very happy with it.
