received them .,fit cards well. not clear to see what' card inside, may be great for unused cards and safe ECT.,if and when to use ,organization as you go out and about., not sure how it was tested ,or to test. Today depends on other views,and walmart/sellers sale/buys.Ect.

I cannot believe how many of my relatives do not have these in their wallet! What a great gift!!! STOCKING STUFFERS - and you can't pay enough for Peace of Mind!

The card sleeves are well made; cards slide effortlessly and fit perfectly in the sleeve. One can still make out the card in the sleeve by the slit at the insert point. I appreciate the bundle pack and the affordable price. I highly recommend them.

With today's easy credit card readers that can read your information while the card is still in your pocket, any weapon against such efforts are welcome

I bought these to protect my credit cards from being scanned by scammers. They work. I highly recommend using them for all your creditcards that can be used by tapping them on a machine.

These are nice, but I don't have a way to test whether they block signals. But they are durable and keep your cards from getting damaged

I loved the appearance of the RFID sleeves . Although I don't know of a way to test them at home, Next time I'm at a store I will. if they don't I'll let you know with an amendment.

I eat these all the time, they are very good and tasty, I eat them all the time.

looks well made and should hold up well. the only problem is the size is a little large and doesn't fit in my wallet slots.

Not worth the money, too hard to get carts in and out of very hard to separate to get the card in not worth it !!!
