The Helmet Diamond Glass 4D is a tempered glass screen protector designed specifically for the Xiaomi Redmi 9A and 9C. It provides full coverage of the front display, ensuring that the entire surface is shielded from daily wear and tear while maintaining the original touch sensitivity of your device. Constructed to be shock, scratch, and dust resistant, this black-bordered protector helps keep your screen intact during accidental drops or when kept in a pocket with keys. An anti-fingerprint and grease-resistant coating keeps the glass clear from smudges, making it easier to maintain a clean view. You can apply it without worrying about trapped air, as it is engineered for a bubble-free installation.
