The Vevor Faraday box is designed to help protect keyless entry vehicles by blocking signals from car keys, phones, and other electronic devices. Its multi-layer construction combines PU leather, density board, and nickel-copper RFID shielding for strong signal isolation. The box supports storage for 5 to 8 car keys and can also hold small items like phones or credit cards. A metal buckle locking seal helps keep the lid securely closed for effective shielding. Compact and lightweight, it is built for home, work, or travel use.
