So I bought this to replace my old foldable bike bag. I like the wallet. I'm not a big fan of this stuff but it seems like it will last a long time. It's a strange rubberized material. I cut out some unnecessary cards from my previous purse to avoid overloading it. The whole point is to keep it nice and thin. The way the card slots are cut out is beautiful. It's very easy to organize your everyday cards and make them easily accessible. My only complaint is that the card slots are very narrow. I sometimes fiddle around trying to reinsert the card. Although they can become loose over time. Maybe that's how you hold onto them. Good wallet for a person trying to keep them minimal. Definitely not for a guy with a bunch of stuff in his wallet. Cannot be expanded with more cards.
