The tempered glass by 3MK is a hardened glass, specially designed to cover and protect your phone's screen from scratches and other damage. It does not affect the screen's functionality. In case of a phone drop, it does not guarantee that the screen will not break along with it, however, it is an additional protection. It is a combination of tempered glass and protective film, as it has a ceramic coating for hardness like glass but also slight elasticity like film. Resistant to scratches, repels fingerprints but reflects light. More durable than tempered glass. It is compatible with Mi 9 Lite.
