9H surface hardness on the protective film delivers scratch resistance up to three times higher than ordinary films, helping protect the screen from daily wear and potential damage. Lens cover and protective case are made from foodgrade silicone, soft and elastic, designed to absorb impacts and cushion the device in everyday use. Accurately cut button holes provide smooth, reliable operation; button feel is preserved, and all functions remain fully accessible without affecting radio performance, heat dissipation, or sensors. Precise hole adaptation achieved through realdevice molding; front screen, rear screen, microphones, loudspeaker, color temperature sensor, and other functional openings are accurately reserved, with a manufacturing tolerance of ±0.1 mm. Use scenarios: Daily protection for smartphones or similar devices during commuting, work, and casual use, reducing the risk of scratches on the screen and body. Photography or video calls where camera and microphone access must remain unobstructed, while the lens cover and openings protect against dust and impact. Outdoor activities or active use where the silicone case provides additional shock absorption and the precise openings ensure full access to all ports, sensors, and controls.
