This 0.33mm thickness glass screen protector prevents sharp objects from damaging the screen while providing powerful shock absorption. It offers an excellent combination of clarity and protection, and if broken, the glass shatters into small, non-sharp pieces. Even sharp objects such as knives and keys will not scratch the glass. Dustproof and durable, it enhances the sense of handwriting and allows for easy installation and removal without leaving any scratches on the screen.
