SMARTDEVIL Tempered Glass 9h for iPhone 13 Pro, 6.1 inch Set of 2 Pieces Product Description: Keep your iPhone 13 Pro private and secure with a set of two SmartDevil tempered lenses with 9H hardness. This innovative protective glass is designed for users who value discretion – thanks to a special coating, the screen is visible only to the person looking directly at the phone. Simply rotate the device 23 degrees to make the image invisible to outsiders. This is ideal for public places such as buses, metros or elevators.
