Precise and unobtrusive operation: Button holes fit accurately, preserving tactile feel and ensuring all device functions operate normally without interference to radio reception, heat dissipation, or sensor performance. Foodgrade silicone protection: Lens cover and protective case are made from soft, elastic foodgrade silicone that can absorb impacts and protect against shocks. Exact hole alignment using realmachine molding: Front screen, rear screen, microphones, loudspeaker, color temperature sensor, and other functional holes are accurately reserved. Tolerance is controlled within ±0.1 mm to maintain flawless compatibility. scratch resistance: The protective film achieves a hardness of 9H, delivering roughly triple the scratch resistance of ordinary films and resisting scratches from keys and other common objects. Durable materials and reliable protection: Combines soft silicone protection with a hardness screen film to guard against daily wear while maintaining device usability and appearance. Compatibility and performance emphasis: Designed to preserve full functionality of controls, sensors, and components, with a focus on fit, material quality, and protective performance. Use scenarios Daily use at home or in the office: Protects screens and sensitive sensors while keeping all functions responsive and accessible. Outdoor activities and commutes: Absorbs shocks and resists scratches during travel, biking, hiking, or other active settings. Travel and workplace environments: Reduces risk of damage from bumps and knocks in transit or busy work spaces, while maintaining device integrity and performance. Key features recap Material: Foodgrade silicone for lens cover and protective case; hardness protective film (9H) Function: Accurate hole reservation for front/rear screens, microphones, loudspeaker, and color temperature sensor Fit: Hole tolerance within ±0.1 mm Benefit: Maintains normal device operation, protects against impact and scratches, and supports longterm durability
