Premium Tactical Glass Shield 5D glass for the best display protection. The glass also protects the curved edges of the display and adheres to its entire surface. Thanks to this, the adhesion to the phone screen 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. In addition, the glass is factory-coated with an oleophobic treatment that prevents fingerprints from sticking, is very easy to clean and reliably repels water. After installing the glass, there is no deterioration of the tactile properties of the display or distortion of the color rendering of the display. The package includes an alcohol wipe for cleaning and degreasing the display, a microfibre cloth for perfect polishing before installation and also afterwards when using the phone with already glued glass.

It sticks to the entire surface and thus prevents the formation of bubbles and the penetration of dirt under the glass. 2.5D glass has the same properties as 5D, but with the difference that it is straight, does not cover the curved parts of the display and usually ends at the point where the display stops being perfectly flat Instructions for gluing glass Clean the display as carefully as possible with the enclosed cloth soaked in alcohol. After drying, polish the surface of the display with the enclosed microfiber cloth. Before placing the glass on the display, make sure that there is no dirt left on the display, even the smallest, that would prevent the glass from adhering perfectly. Also pay attention to the places around the handset, where dust and dirt often get stuck, which would degrade the glass. Carefully place the glass over the display so that the cutouts for the camera, earpiece or proximity sensor overlap exactly and the glass is perfectly centered vertically and horizontally. Then press the glass onto the display and push air from the center to the edges.
