This specific tempered glass has adhesive on its entire surface, meaning it is Full Glue, which makes it very stable and more difficult to detach. Protect your mobile phone screen from hard scratches and impacts with the TEMPERED GLASS SCREEN PROTECTOR 0.30mm from VOLTE-TEL. With a thickness of 0.30mm, it has excellent transparency and does not affect the contrast, brightness, and colors of the screen. It has a high hardness rating of 9H, making it very difficult to break or scratch, especially compared to regular screen protectors. It is made with precision-rounded edges of 2.5D for greater safety and to prevent injuries. In the event of a strong impact causing it to break, it shatters into very small pieces without scattering, similar to a car windshield, to avoid any risk of user injury or screen scratching. Lastly, due to its construction material, you are free from the unsightly bubbles that can easily form when using regular protectors, as it perfectly and easily adheres to your smartphone screen.
