Glass anti-scratch Screen Protector. Made from glass that has undergone special thermal treatment to increase its resistance to impacts, scratches, and other types of damage. The material is such that even sharp objects like keys will not "hurt" the phone screen. The oleophobic coating removes fingerprints and smudges, making it easy to clean. The perimeter surface of the glass has been treated so that the screen protector's edge does not protrude and is smooth. The product is environmentally friendly and does not cause pollution. It features a special protective cover against fingerprints and liquids such as oil, water, and acids.
