The screen protector by Bigben Interactive 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 3D, which means it has undergone special processing to acquire curved edges that will cover the entire surface of the phone screen. This way it is not apparent that the screen has protection, but additionally, the curved edges are also protected. It is compatible with Redmi Note 15 / Poco M8.
