I like small wallets that will fit in my front pocket. This is slightly larger than a credit card, and I'd say medium thickness (1/2" or so with a couple of cards and some bills inside the folded portion). It's quality. The mechanism for fanning out the cards is great. Unless I need to get cash, I never actually unfold the wallet, just slide the mechanism...which can be done one-handed easily. I was tempted to buy the cardslide instead of this but I wanted leather, and this is quality leather. Recommended.
