This mobile protective film is an unbreakable membrane designed for iPhones, offering high transparency and anti-scratch properties. It ensures a bubble-free application and is anti-shatter, protecting against oil stains and fingerprints while providing a perfect tactile feeling. The screen protector is extremely thin, measuring 0.15 mm, and is easy to use, offering 360-degree full package protection. It is a flexible TPU screen protector, not glass, specifically designed to cover the curved edges of your device for edge-to-edge protection. Any small air bubbles or pressure streaks will naturally disappear within 1 to 2 days after installation. The installation process involves cleaning the phone surface, peeling off the No. 1 film, aligning the protector, tearing off the No. 2 inner release film and sticking with a card, tearing off the remaining No. 3 inner release film, and finally tearing off the surface release film.
