It did job what it promised

Not worth it and don't work waste of money

Hope they work …I use them

I really like these cards to protect my contactless payment cards in my wallet, just slip them so they are between the card and the outside of your wallet. I even tested them in stores with the card between the payment unit and my payment card, they worked either it couldn't read anything or said there was a card reading error which is what you want.

Not what I thought they must be in front of cards. I thought you slid your card in side to protect them.

Llega lo que promete, llegó muy rápido, falta comprobar su funcionalidad
