Me encantó, love it, looks stylish and feels like a very good quality product made of leather, so far no problems with the size of my cards fitting on it. Only seems to be like top up once you put a lot inside it if not just regular size wallet even a little bit smaller than a regular one

Great wallet but its a snug fit
Size: One Size, Color: Black (Hunter)
Listen to the other reviews! This wallet is ALMOST perfect. It came in 2 days without prime, looks amazing, is slim, and has everything you need in a wallet, except for space. Not that it doesnt have a bunch of card slots because it does, but you cant get the cards in them! It is real leather which is great but it also means its tight. My husband could only fit one card in each slot. He tried to put two cards in the side slots and now we cant get them out. The id slot is a tight fit and the plastic window is so small that once we actually got his license in it, it cuts off his birthday and other important details so he will have to take it out in order to show it, which takes about 2 minutes to remove it. Knowing how real leather works, I know it will stretch out but for the time being I feel bad for whoever is behind him in line. Other than that its a great wallet and he loves the look, feel, and the fact that it has the 2 cash pockets. If it wasnt for the tight fit, it would be 5 stars.
