It's a pleasing solution for me. The slim, pocketed design fits well in my front pocket. It probably fits other pockets well too. It's not perfect. But, it's solving for an imperfect solution that Apple is takling with their phones. Tap to pay with phones and digital ID will change the market for wallets. The physical size of cards limits how readily you can access any one card. It takes a bit of extra dexterity to pinch or slide some of the cards out. Ideally you'd have 4 on the outside, with remaining cards tucked in the center pocket. I just need more than 1/4 inch of card face to slide one out readily.

It’s not a thick wallet, which is what my husband likes. Makes sitting or driving for long periods with it in his back pocket better. Has everything larger wallets have. Will purchase it again.
