Genuine leather with RFID protection

Received this genuine leather card holder for free with a Citizen promotion. I was surprised that this card holder is also RFID protected to keep your credit cards, etc safe from fraudsters. Both sides have two slots and the top has an opening where you can maybe fold a couple of paper money or other thin items there. It’s a nice option to carry when you know you do not have to bring your chunky wallet with you or in addition to a regular wallet but keeping some additional cards with you that may not fit in your regular wallet. Can put ID, credit/bank cards and little paper cash in there.
