New Full Cover Tempered Glass technology 21D, with adhesive across its entire surface and curved edges to "fit" perfectly on the screen.

It is stable and does not affect the contrast, brightness, colors, or sensitivity of the screen at all. Also, with its curved "edges," it is compatible with almost all cases available on the market.

Installation is very easy, unlike common 5D and 9D glass protectors, and it does not leave unsightly bubbles that can easily form on others.

This is the best protection for your mobile phone's screen!
