The Helmet Diamond Glass 5D is a protective screen protector designed specifically for the OPPO Reno 13 F/FS. It uses tempered glass with a 9H hardness rating and specialized Diamond Glass technology to provide a strong barrier against shocks, scratches, and dust. The 5D curved edges ensure the glass follows the contours of the display for full screen coverage, while its ultra-thin profile maintains the original touch responsiveness of your device. To keep the screen clear, an oleophobic coating is applied to reduce the buildup of grease and fingerprints. This high-transparency layer ensures that the colors of your display remain accurate and vivid. Because of its precise fit, this protector works well with most phone cases, making it a practical choice for anyone wanting to keep their screen pristine during daily use.
