Premium Tactical Glass Shield 5D for the best screen protection. The glass even protects the curved edges of the screen and adheres to the entire surface. The adhesion to the phone screen is perfect and bubble-free. The thickness of the glass is 0.33 mm, making it practically invisible on the screen, but thanks to the 9H hardness, it is strong and durable enough to protect the phone screen in case of accidental drops or minor scratches. The 9H hardness of the glass indicates the Mohs scale of mineral hardness. The scale ranges from 1 to 10, where 10 indicates the hardness of a diamond. The scale is represented only by numbers without the "H" suffix. The "H" suffix represents the hardness of graphite. Thus, "H" means that the protective glass is harder than this type of graphite. The surface has an oleophobic coating that prevents fingerprints and oil stains as well as water and is very easy to clean. After installing the glass, the touch properties of the screen do not deteriorate and colors remain vivid.
