Premium Tactical Glass Shield 5D for the best screen protection. The glass protects even the curved edges of the display. Adhesion to the phone display is perfect and bubble-free. The thickness of the glass is 0.33 mm, so it is practically indistinguishable on the display, but thanks to the 9H hardness, it is strong and durable enough to protect the phone's display in the event of an accidental fall or minor scratches. Glass hardness 9H indicates the Mohs scale of mineral hardness. It ranges from 1 to 10, where 10 indicates the hardness of the diamond. The scale is represented only by numbers without the "H" suffix. The suffix H stands for graphite hardness. So the H means that the protective glass is harder than this type of graphite. The surface has an oleophobic coating which prevents fingerprint and oil stains as well as water and is very easy to clean. After installing the glass, the touch properties of the display do not deteriorate and the colors of the display are not distorted. The package includes an alcohol wipe for cleaning and degreasing the display, a microfiber cloth for perfect polishing before installation and also with already glued glass.
