The screen protector by GrizzGlass is a film, specially designed to protect the screen only from dust and superficial scratches. It does not protect the screen in case of a drop, as it is thin. It does not affect the screen's functionality. 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 Xperia 1 VII. See full description
