The screen protector 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. Flexible, made of hydrogel, it is easily applied without forming bubbles and self-repairs from scratches. Provides excellent clarity but also increased reflections. It is compatible with Redmi Note 9S / 9 Pro / 9 Pro Max.
