Protect your tablet screen with anti-scratch glass with a high hardness of 9H. Tempered Glass is baked glass that is heated to a high temperature and then cooled rapidly, a process that increases the hardness of the glass. The 9H hardness screen protector offers protection from the sharpest objects, while at just 0.3mm thickness it does not add bulk to your device. At the same time, it provides 100% clarity and an excellent touch feel.
