Crong Glass Edge is a dustproof tempered glass with a full adhesive layer for the phone screen. Full-surface adhesive guarantees excellent adhesion of the protective glass to the display. As a result, the smartphone retains optimal touch response and is better protected. The full-surface adhesive layer also prevents dust and dirt particles from penetrating, which guarantees worry-free and comfortable use of the phone over a long period of time. The minimal friction is due to the perfectly smooth oleophobic coating, which is also responsible for the Glass Edge glass' increased resistance to grease spots and stains. The 9H (Moss scale) hardness level guarantees extremely high resistance to scratches from sharp objects. Each glass is laser-cut to precisely replicate the shape of the screen and fit the glass to the selected smartphone model.
