Holographic RFID Blocking Card Holders (10-pack)

These amazing Holographic Vertical RFID Blocking Card Sleeves are a must - have for safeguarding your RFID - enabled cards like credit cards, bank cards, and photo IDs from identity theft. They work far better than wrapping your cards in aluminum foil. The sleeves protect the Radio Frequency Identification (RFID) chip of your cards from unauthorized access by potentially malicious RFID readers. Each sleeve measures 65mm x 90mm, fitting perfectly into your wallet or purse. You get ten sleeves in a pack, so it's no big deal if you lose one or share it with a friend.

Using these RFID blocking card sleeves is super easy. Just slide your RFID - enabled cards like credit cards, bank cards, or photo IDs into the sleeves. Then you can put the sleeves into your wallet or purse. Remember to keep the sleeves away from sharp objects to avoid tearing. There's no special maintenance required, but if they get dirty, you can gently wipe them with a soft, dry cloth. That's all you need to do to keep your cards safe from identity theft.
