SaiTech IT Set of 20 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)

These each hold a card. They work at blocking RFID signal.

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!

A lot for the money

Everyone needs those for their cards

The next day After received my package , I went to the gas station to check if the tap card reader would read my card while is in the RFID card holder sleeve, but it didn’t read it. I recommend it very gooooooooooood😎

It's a good value for the price, but I honestly can't tell if it's been effective at what it's made to do - simply by the nature of RFID theft. Since I haven't had any issues, I'm assuming it's protecting my cards. The one issue I have with them is that one side should be notched lower than the other so that it is easy to reinsert the card. I've often been flustered at cash registers trying to put my card back in one of these sleeves because I can't open them without a lot of fussing. Lowering the notch on one side would make it much much easier.

They are much bigger than the card itself and don't fit my wallet very well.

I like these for all of my credit cards due to the security.

sirven para llevar ordenada la maleta, lo único es no llenar las bolas con muchos artículos ya q se llegas a romper

Material sencillo.Cubren por completo la tarjeta.Hasta el momento todo bien.

Llegaron antes e tiempo, muy bueno

The pouch is very good and its indeed very uselful for protecting the cards from wear and tear aswell.Imortant specs:Its fitting the cards perfectly.Nouch will help remove the cards from the sleeve faster.May be little bigger for some wallet credit card slots (cutting the extra edges from sides will do)

las tarjetas entran perfecto en esta funda, ni muy justa ni muy suelta por si las guardas en una mochila, para una cartera sirven pero necesitas recortarla un poquito, nada difícil pero a tomar en cuenta
