Calvin Klein RFID Wallet Black

I have this RFID(Radio-Frequency identification) Calvin Klein wallet up for sale. Anyone not familiar with RFID , it is basically a layer of protection to block the electromagnetic signal emitted from your bank Tap cards, to protect against electronic pick pockets with skimming devices in attempt to steal your hard earned money. I have never used it, it’s practically brand new, the way I purchased it in the box is the way it’s remained until taking these pictures to post it up for sale. It has 6 single card slots, 2 slots for cash, and 2 slots behind the card slots one on each side.
