Prima Executive Money Clip with Credit Card Slots, from the Green Collection, has a spring tension clip and divider for currency, as well as credit card slots. It is functional, compact, and able to fit in most regular sized pockets with ease.
PROS: My husband hates to carry a wallet - he likes this style very much. He feels the magnetic version doesn't hold like the tension ones. He threw away his old taped wallet and gleefully arranged the new one I got for him. He is extremely happy for the functionality and I love the look.
