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.

Fit in pocket
Color: Dark Gray, Style: Classic
Bought as a gift. My husband really liked it, held all his cards. The leather was very nice. Color was very soft gray and I liked it better than the normal black or brown. Wallet fit well into his back pocket.
