Are you perceiving that your billfold /wallet was contains mostly credit cards and credit-card sized cards, such as driver's licenses, loyalty cards, insurance cards, and business cards? There was hardly any "bills to fold," so why you carry a billfold? If you examine some of the pocketbooks that women carry in their purses, many of them will hold a checkbook, and they were too large to fit in your pants pocket comfy (plus some of them look feminine). This does not look feminine (in black)... you would say unisex.
This is an attractive, elegant and versatile cardholder case that has ten individual slots for cards, plus a wider slot on each end that you can use for cash or receipts. You can put 1-2 cards in each slot. It is slightly smaller than your old billfold, and the zipper closure ensures that nothing falls out. There is some flexible shielding inside them.
