The listing, Credit Card Sleeve has ended.
Many new credit cards use microchips with RFID technology that can transmit your personal data. Protect your credit cards with an RFID Protection Card Sleeve. Made of tough Tyvek material that's tear and water resistant, the sleeves prevent damage to your card's magnetic strip. Thin and lightweight, the 2-pack of Credit Card Sleeves (picture above) feature a thumb cutout for easy access to your credit cards. Just so anyone doesn't get confused, this is only for one sleeve, just like the title.
