RFID Blocking Sleeves Set Credit Card Protector, Top Identity Theft Protection Travel Case (Bundle of 12)

These are cardboard with a type of metallic lining. They are a snug fit over credit cards- a challenge to the cuticles ;-) Then, when you try to put the card back in it''s slot in your wallet or purse, it wont quite go in. You need a fair amount of force. This does not go well with manicures! I decided to cut the corners (at the open end) and it made a big difference. Overall okay but not great. Very good price.

Great idea & good value for money. My only criticism is that they are a bit of a snug fit in most purse & wallet card slots and could therefore do with some sort of reinforcing around the top to prevent the edge of the slit from getting dog-eared in use. However at the price they aren’t going to be expensive to replace.

These block everything from my oyster card to be credit cards from working when they're protected by the wallets, and fit fine inside my cash wallet for day to day use, and provide reassurance that my cards are protected from thieves armed with card readers, or getting caught out by the card reader on london buses!

Arrived on time. Good value for money.

Seem to work fine but do not fit in all wallets

A little bulky but cards fit into them well.

We are using, appear to protect as stated

Bought two lots of these as gave some to various family members as well as using some ourselves. Great product and does what they are meant to do.
