Well made,
The leather is flawless, all the stitching is well done, the ability to organize my cards in groups worked out well. It's overall size is fine, fits well in a front pocket, flatter than a tri-fold, not bulky. My only wish would be making the width of the inner double sided leather card holder page pockets just 1/8" wider. In my opinion this would then be a 5-star wallet. One spot to hold some of the just wider than credit card size for easy access would be nice. Besides that, I intend to use it until it is worn out. Nice wallet!

Size matters
Color: Derrick Dark Brown, Size: One Size
The quality of the wallet is fine, but the size… it’s way to big to fit in a man’s pocket easily. I should’ve done a better job reading the measurements, but dang!

Nice looking wallet with two currency pockets and plenty of room for credit cards, etc.
Color: Derrick Dark Brown, Size: One Size
This is a truly great looking wallet. I have carried a "man-purse" (for lack of a better term) for years and have always carried a normal bi-fold wallet in it. There is room for this larger wallet, so I decided to give this one a try. So glad I did. I like the way it looks, love the RFID ability and enjoy the easy access to all credit and ID cards I need to carry. Some of the credit card slots are initially very, very tight, but I'm sure they will become easier to access with time and use. Because they are so tight now, I am aslo quite sure they will stay tight enough to hold cards securely after much usage. This is larger than the traditional style of men's wallet, so please be aware of that if you decide to buy one.
