SaiTech IT Set of 10 RFID Blocking Sleeves Best way to Protect your Cards from Electronic Theft, Durable, Lightweight and Compact Design to fit in any Pocket or Purse (Silver)

They work! I decided to get these after I sat my wallet on the counter at a convenience store and it scanned through my thick wallet and charged my card. I tried using the tap with this sleeve on to make a purchase and it couldn't scan. So it works and it comes with a bunch of sleeves

Worth every penny. Everyone should have these to protect their credit cards. They are super thin and take up no extra space. Having purchased them a while back, they are durable and removed our worries about unprotected credit cards.

I have used this type of protector for years with no problem until the protector itself got tired.So I order new ones and I will see how long they last. Great idea.

Good price

I didn’t need 10 so I have given some to friends

I received it, a month ago everything else is good. It's fits with my credit card. I'm satisfied with it. I like the design and more secure. Thanks you Amazon

I presume these card holders do what they are supposed to, but who ever knows for sure. My issue is they are difficult to get the cards into as the fit is tight and the opening is uniform height across the top, front to back, so the slot is hard to find. I ended up cutting out a portion of one side of the top in order to distinguish where the opening is and then using scotch tape attached in a loop front to back on the top of the card to make it easier to get it out of the sleeve. This was not an issue with previous sleeves I have used so it did not occur to me that it would even be an issue!

They really do work, I gave some to my family.
