This is a well constructed wallet and they used good material
Color: Coffee Brown, Style: Casual
I really like the leather, and all the compartments for the credit cards and two IDs. The only issue I’ve had with this wallet is it’s just a little too high. Should be a quarter of an inch shorter because it’s awkward putting it in and out of your your pocket.
