The mobile screen protector is made of glass that has undergone special heat treatment to increase its resistance to impacts, scratches, and other types of damage. It protects the entire screen, including even the curved parts. The perimeter surface of the glass has been treated (special grinding) so that the edges of the screen protector do not protrude and are smooth. Additionally, it features a special coating to protect against fingerprints and liquids such as oil, water, and acids.
