You'll either love or hate this design, because there's nothing to keep either your cards or your cash in place when you open up the wallet. So if you drop your wallet, all your cards are likely to spill out. This is what gives it the capacity to hold a lot of both, but it's also what makes using the wallet very manual. The best way I've found to get cash, for example, is to open the wallet sideways, grab the bill you want with one hand, and then use your other hand to hold the rest in place while you pull them out. If the bills aren't beside each other, you'll have to take them out one at a time. This means the wallet is a card wallet. However, getting into your cards also isn't as optimized as it is with most other wallets. You can only hold the wallet loosely to let your fingers be able to get into the cards (not squeeze it to open it more), and then the wallet opens up far less than you'd expect. This is not much of an issue, though. By arranging your cards smartly, you can still comfortably access your four most used ones. In summary, this wallet is for people who primarily use cards but nonetheless don't wish to fold their bills. I'm one such person, so I actually grew to rather like this wallet in the days I've been using it, despite its inconveniences. There's no other wallet which functions like this one in my collection, for better and for worse. It's unfortunately a little too simple, hence why I cannot recommend it for most people despite liking it myself. That being said, if you are a collector like I am, I think this is something worth adding to your collection.
