The Helmet Diamond Glass 5D is a tempered glass screen protector specifically designed for the OnePlus Nord 3 to keep the front display safe from daily wear. With a hardness rating of 9H, this protector guards against scratches, shocks, and dust, while its 0.3 mm thickness ensures that the device remains slim in your hand. Its 5D full coverage extends to the curved edges of the screen, blending seamlessly with the black border for a discreet look. The ultra-transparent glass maintains high optical clarity without distortion, so you can enjoy the display's original colors. A specialized surface treatment resists fingerprints and smudges, keeping the screen clean, while the high sensitivity allows for precise touch interactions during use.
