The PanzerGlass™ anti-glare screen protector for the iPhone 13 Pro Max in black features the same essential advantages as the original PanzerGlass™ screen protector. It effectively reduces sun glare when your phone is used outdoors or in brightly lit environments. This screen protector has an active antimicrobial coating that resists bacterial and fungal spores. The antimicrobial ingredient kills bacteria and fungal spores on the glass, protecting you as a user. The coating is non-toxic.
