Review on Silent Pocket Faraday Bag Smartphone Sleeve: Ultimate Signal Blocking Shield for Travel & Privacy - Leather/Waterproof Nylon, Anti-Hacking - iPhone, Samsung Galaxy & More - Multiple Colors by Brian Olson

It looks and feels like quality. My phone slides in and out easily. It was difficult to find a model with the sizes I needed, so it's great that the sizes are given in the product description. For my EMI tests, I put a working cell phone inside and closed the lid. I couldn't detect a signal over ambient noise (basically just random neighbors' Wi-Fi) while the phone was closed inside. As soon as the lid is opened, all kinds of EMI signals come out. My only disappointment is that it's not high enough to close my phone's lid when the mic lock is connected. The body size is only about half a centimeter. too short for that. The phone is 15.2 cm high, 7.2 cm wide, 1 cm thick with case. The microphone barrier protrudes 1.7 cm from the top audio jack.
