16 RFID Blocking Sleeves Set (12 Colorful Credit Card Protector RFID Blocking Sleeve & 4 RFID Passport Holder). Effectively Protect Your Credit, Debit, and ID Cards From Electronic Theft.

works very well. in some stores I have to swipe my card to get in. I have tried to swipe it while in the sleeve and it blocks it from reading. have had the sleeve for six months and after much use in my wallet they are still in good condition. all my cards fit snugly in the sleeves so they will not fall out by accident. good value for the price. Am well pleased with them.

.....go ahead and say I've "too much time on my hands" but ?? I am a fast typist so it's not that bad. I ...rushed... yes, and I "DO HAVE 'a life'" to write a review of these. ESPECIALLY if you have an around-the-waist MONEY BELT...from Amazon...one of those 3" x 4,5,6" with elastic belt ???? ...often you're in a PUBLIC place exposing your money belt AND having to rifle through cards to be sure you're pulling out the RIGHT CARD ???? The COLOR CODING helps tremendously. .....Green for favorite MONEY card.......blue for navy related, etc. AND of course while protecting the card RFID-wise WHILE making it easier and faster to pull out the RIGHT CARD... ALSO A PLEASANT SURPRISE: the FOUR (4) sized ones for your PASSPORT !! 'can't beat it especially for the price. Might buy another set for more variety / number of colors.

Love these!! I a small card and ID holder and love how I tell what card is what by the color I put it in. Makes it som easier for me to find a card or ID quickly. Hopefully the blocker is doing its job by protecting my cards from hackers. I hope to never have to find out.

Feel safe knowing someone can't steal my information. Colors are pretty.

These appear to work! I had a cashier try to tap my card while still in the sleeve. It wouldn't work. Since I always had trouble sliding my card back into the sleeve, I cut down a sliver at the top of one side of the opening. Now it's perfect! Fits well in my wallet.

Excellent product. It is exactly as advertised. Very durable. It is not bulky and fits inside wallet card holder with ease. The passport holder is excellent as well. I recommend buying this product.

Great price. A travel and wallet must.

Product is too wide for phone case wallet and other types of wallets. I trimmed the edges to make it fit, but cut the sides in the process of getting it to fit where I use the cards the most. I also agree with other reviews that say it is difficult to open to slide the card in after use.
