Great craftsmanship
It’s a great leather card carrier. The money clip is strong and there is plenty of room for 4-6 cards comfortably. Slim and classy

Customer Customization Required
Color: Black
The money clip wallet is well made and attractive, but as many people have commented, it doesn't hold enough cards. HOWEVER, it can be stretched. I pounded a stack of nine old cards into the wallet and left it in a drawer for four days. After pulling the cards out, it comfortably holds seven. I'm completely satisfied.

Good quality and real nice presentation of the box. Special
Color: Black
It’s good quality and a real strong magnet. It’s bigger than my old one that I’ve used for 20 years. I won’t ever find another one like my old one.
