Luumxai 16 RFID Blocking Sleeves Set (10 Credit Card Holders & 4 Passport Protectors) Identity Theft Protection Secure Sleeves Set.Waterproof aluminum foil slim Design easily into your Wallet

I do not go anywhere with my cards unless I have these to put them in. I tested the ncf and without that RFID sleeve my phone read the card quickly. Once I put the sleeve on the card, nothing. I feel protected with these sleeveson my cards. They are great colors so you have some that are cute and some that are functional. They are thin so as not too create bulk in your wallet. The colors make it easy to keep your wallet organized and they are thick enough that they feel sturdy! Highly recommend.

These are handy protectors for all our RF cards - definitely worth the purchase, especially if you've ever had a card skimmed because you were carrying it, unprotected, in your pocket. We now have all of our cards in these blocking sleeves. The bright colors make them easy to spot in my wallet, too.

Color coding helps keeps cards organized. Good quality. Thick not flimsy and look nice. Material is easy to slide cards in and out of

I deal thing RFID to help keep your credit cards safe when you are traveling are just keep your credit cards safe period

Love this. Perfect for all of my cards. It’s a little bigger in width but it’s still worth having

Bought two packs and handed them out to friends, keeping 2 for myself. Do they work - I don’t know but I haven’t had a problem with credit card data being stolen so I have to trust that they are helping to keep the bad guys away! They fit the standard credit card, simple to use, and take up no space. Price wise they cost very little .good deal.

Though it's said passports are protected "to make it difficult" for perps scan it, I think it's good to err on the side of caution and keep it in the RFID sleeve, which also keeps it clean, etc. Passport CARDS -- Like Credit Cards -- AREN'T protected! The differently colored sleeves are perfect, and easy to know which card is in which color. These are Really Good To Have On Hand (ESPECIALLY for the price!) even if you don't travel a lot or leave home with credit cards all the time. There are also enough passport holders to share with someone else!

Very sturdy but unlike some others I've used the overall size is too large to fit comfortably in the pocket/sleeve in the interior of a men's wallet. Work but annoying.

This item was suggested as the way to protect credit and debit cards from scanning by thieves.

Worked well. Good value for money

These worked perfectly. I tried to pay with the shield on my card and it didn't work, even from very close up to the scanner. Can't get better than that.

They work, and massive variety of colours

Great service prompt good price and exactly what was ordered
