Some might think that it's masculine to carry a wallet like this, but I respectfully disagree. It's literally the perfect wallet for this super slim purses that women love to carry. You can also fit it perfectly into backpacks, messenger bags, briefcases, carryons ... where ever space is limited, you don't want the bulk or the weight (it only weighs a few ounces). If you don't want to put your passport in it, you can use the slots for cash, receipts, parking stubs, business cards, you name it. The fact that it's RFID blocking is now an absolute must in today's world.
