Premium Tactical Glass Shield 5D for the best screen protection. The glass protects even the curved edges of the screen. It adheres to the mobile screen perfectly and without bubbles. The thickness of the glass is 0.33 mm, making it practically unnoticeable on the screen, but thanks to the 9H hardness, it is strong and durable enough to protect the mobile screen in case of accidental drops or minor scratches. The 9H glass hardness indicates the Mohs scale of mineral hardness. This scale ranges from 1 to 10, where 10 indicates the hardness of a diamond. The scale is represented solely by numbers without the "H" suffix. The "H" suffix refers to the hardness of graphite. Therefore, "H" means that the protective glass is harder than graphite of this type. The surface has an oleophobic coating that prevents fingerprints and oil stains as well as water, making it very easy to clean. After installing the glass, the aesthetic properties of the screen are not compromised, and screen colors are not distorted.
