The tempered glass of 3MK is a hardened glass, specially made to cover and protect the screen of your mobile phone from scratches and other damages. It does not affect the functionality of the screen. In case of a drop, it does not guarantee that the screen will not break along with it, however, it provides an additional protection. It is a combination of tempered glass and protective membrane, as it has a ceramic coating for hardness like glass but also light elasticity like a membrane. It is scratch-resistant, repels fingerprints but reflects light. More durable than tempered glass. It is compatible with Xperia 10 III.
