Product features:
1. The surface of the product is made of special carbon fibre material, which is more durable and long-lasting. The products are produced by professional production staff using specialised machinery, and the stitching does not come undone. The metal clasp ensures that the box is closed and easy to use.
2. High-density metal mesh with a diameter of less than 0.12mm is used as the electromagnetic shielding material, and all products have been tested twice before leaving the factory. The shielding capacity of this signal shielding box for various electromagnetic signals can reach more than 99.9%.
3. As well as holding your car's keys, you can also put your mobile phone in it while you sleep to avoid being disturbed by night-time calls. As opposed to just switching your mobile phone off, when the other person calls, they will be alerted to the fact that you are in an area with poor reception or be redirected.
4. It can also be used to store unused electronic devices, shielding them from signal location that may exist even when they are switched off, and preventing leakage of personal location information.

Note: When in use, make sure the box has a latch that closes properly. This product has not been specifically designed to be waterproof, please avoid liquid splashes or rain from entering and affecting the items stored inside.

Box size: 17* 12* 9.5 cm / 6.7* 4.7* 3.7 in
