2PCS Faraday Bags for Car Keys and Cell Phone, RFID Signal Blocking Bag, Keyless Entry Fob Signal Blocking Pouch, Cell Phone Privacy Card Protection, Anti Radiation Key Pouch (Black)

Super fast Service! Functional, Easy to use, good value, thanks

These work like they are supposed to! I put my phone in one and called myself on my husband's phone and it did not go through. Plenty of room for the big phones with cases. Happy with this purchase.

works great

These bags really blocked the signal well on my iPhone. No ringing at all.

Tried both bags and they did not ! Work

As far as I can tell, out of the box they block signals as described. But the quality compared to others I've had is not that great. I bought because of reviews saying they were spacious enough for large phones and the material quality was very good. Neither are true. The size barely fits the smaller of my two phones lengthwise and the material I will be surprised if it holds up long, especially considering it barely fitting my device. I guess I got what I paid for.

Excelente 👌 👌 👌

Works great, does the job.
