The Helmet Diamond Glass 4D is a tempered glass screen protector specifically designed for the Huawei P40 to keep the front display safe from daily wear. Its 4D curved edges ensure the glass follows the contours of the screen for full coverage, while the black finish blends seamlessly with the device's borders. This protector focuses on durability by offering resistance against scratches, shocks, and dust, which helps maintain the phone's condition over time. An anti-fingerprint coating keeps the surface clean, and the high optical transparency ensures that the screen's original clarity remains undisturbed. Thanks to its bubble-free ergonomic design, you can apply it smoothly to the front screen without worrying about trapped air.
