The Tempered Glass Screen Protector for your device is an anti-shatter film that sits on top of your tablet screen and offers the best protection for your phone. Screen impact is dissipated over the tempered glass surface to manage extreme pressure if the phone is dropped or knocked in your bag. This hardness rating offers superior protection and scratch resistance to sharp objects such as keys, coin edges and stones. It will not scratch as easily as your regular PET screen guards.
