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.

Great wallet

I’ve tried several of these money clip wallets, after an older one I loved finally fell apart, and this one is much the best I’ve found. Great magnet (really clamps down on cash), room for 8-10 cards. Not too big, not too small. Quality. Very happy, may even buy another to put aside for when this one eventually goes.
