The Tempered Glass screen protector for Lenovo TB311 is made from tempered glass, which is heated to a high temperature and rapidly cooled, a process that increases its hardness. It has a hardness rating of 9H and protects the screen from scratches and sharp objects.

At 0.3 mm thick, it does not add bulk to the device, while the glass preserves the screen’s clarity and touch sensitivity.
