The Helmet Diamond Glass 5D is a full-coverage screen protector designed specifically for the Oppo A78 4G and Oppo 8T. Made from high-quality tempered glass, it extends across the entire surface of the display to protect even the curved edges from daily wear. This protector guards your device against scratches, shocks, and dust while maintaining a precise touch response thanks to its ultra-thin profile. The black finish blends seamlessly with the phone's bezel, and the bubble-free application process ensures a clean installation for anyone looking to keep their screen in pristine condition.
