The full face tempered glass is a full coverage hardened glass specially designed to protect the mobile phone screen from scratches and other damages. In case of dropping the phone, it provides additional protection, although it does not guarantee that the screen will not break. It does not affect the screen's functionality.

The black border covers the entire surface of the screen, including the edges. It features adhesive across the whole surface, unlike edge glue glass protectors which only have adhesive along the perimeter. This ensures better application and proper touch screen operation. Additionally, it prevents dust from passing underneath, which can happen with edge glue protectors when the perimeter glue wears out.

It can be removed at any time without leaving marks or causing issues to the screen.
