For years we thought you could just put your wallet in your back pocket and sit down. Men did this for decades without realising that over time it cuts off the circulation in your legs. Research is just now starting to say this is very bad for you. But this metal card wallet acts as a holder for men or women's credit cards that slips easily into a pocket. After you switch to this, you will always stay with a card holder that's portable and functional.
Material: PU leather + aluminum alloy box
