Upgrade version here! The TechProtectus Lockable Signal-Blocking Pouch combines a patent  mechanical locking technology with an inner Faraday shielding layer to keep student phones fully secure during class. Once shut, the pouch locks instantly and stays closed until a teacher unlocks it using the base key — which comes in both portable and wall-mounted options.

The Faraday lining blocks all wireless signals — calls, texts, Wi-Fi, and Bluetooth — while the rugged outer construction is built to withstand daily use in schools
