The screen protector by 3MK 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. 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 Nothing CMF Phone 1, 3mk. See full description
