This particular tempered glass has adhesive on its entire surface, meaning it is Full Glue, which makes it very stable and harder to detach.

Protect your mobile 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 clarity and does not alter the contrast, brightness, or colors of the screen at all. It has a high hardness level of 9H, making it very difficult to break or even scratch, especially compared to regular screen protectors. 

It is made with high-precision rounded edges 2.5D for greater safety and to avoid injuries, and in case it breaks from a very strong impact, it shatters into very small pieces without scattering, just like a car windshield, so there is no risk of injury to the user or scratching the screen. 

Finally, due to its construction material, you are spared from unsightly bubbles that can easily form when using regular protectors, as it fits perfectly and very easily on your smartphone screen.
