The full face tempered glass by Techwave is a full coverage tempered glass, specially designed to protect the mobile screen from scratches and other damages. The black border covers the entire surface of the screen, including the edges. It is 10D, meaning it has undergone special treatment to achieve curved edges, covering the entire surface of the mobile phone screen. With this design, it is not noticeable that the screen has protection, while also protecting the curved edges. It is compatible with the Redmi Note 13 4G.
