Blue Star tempered glass with 9H hardness is an extension of the life of your device's screen. With an extremely low thickness of 0.3mm, it is virtually imperceptible and invisible and provides 100% tactile value and freedom of use. The glass perfectly protects the screen of the device from cracks, scratches and damage. The oleophobic coating ensures the transparency of the screen and resistance to fingerprints and dirt. The glass comes with elements necessary for self-assembly along with special stickers to facilitate the proper arrangement of the glass. After application, thanks to the entire adhesive surface, the glass adheres perfectly to the screen without leaving air bubbles, and the adhesive-free formula makes it easy to remove the glass without leaving any residue.
