The tempered glass by Premium 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. Its matte coating prevents fingerprints on its surface, as well as light reflection. In some cases, it may limit screen clarity. It is compatible with iPhone 6 / 6S Plus. See full description
