The full face tempered glass by Wozinsky is a full-coverage tempered glass, specially designed to protect your phone screen from scratches and other damages. In case of a phone drop, it does not guarantee that the screen will not break along with it, but it is an additional protection. It does not affect the screen's functionality. It has adhesive all over its surface, unlike edge glue glasses that have adhesive only on their perimeter. This helps in better fitting and the seamless operation of the touch screen. It also prevents dust from getting underneath, which can happen with edge glue when the perimeter adhesive wears out. It is compatible with the iPhone 13 / 13 Pro.
