Instantly Block: Cellular, WiFi, Bluetooth, GPS, RFID, NFC, Satellite, Navigation, EMP, Solar Flare, Key Fob and EMF Radiation I have a iPhone 14 Pro and I bought this new, and it works really well when testing it with my EMF detector. I used it only a few times but it's like new, in perfect condition. It is too big for a back pocket, that's why I'm selling. I have a phone case that covers my phone and it fit perfectly. I bought this directly from Faraday and a photo of the invoice is included. It costs 87.95 (including tax and shipping).
