Kalebol Metal Convex Hollow Lens Protector Ring 1. Material Upgrade, Aluminum Alloy Protection: Made of aluminum alloy (industry hardness benchmark), the anti-drop and wear-resistant performance is comprehensively improved, long-lasting resistance to bumps and scratches, and provides a strong protective layer for the lens. 2. Strong adsorption, no traces in seconds: Innovative high-adhesion adsorption technology, the film automatically exhausts air bubbles without residue, tightly fits without displacement, significantly reducing the risk of falling off. 3. Full wrapping anti-fouling design: complete coverage of the lens surface, edge protection without dead ends; superimposed hydrophobic oleophobic coating, anti-fingerprints and anti-oil stains, wipe clean without leaving traces. 4. Non-destructive image quality, light transmission like a mirror: high transmittance glass substrate, the refractive index of light is close to the bare mirror, photovideo imaging without blurring, no noise, true color reproduction. 5. Exclusive openings, precise alignment: laser cut holes according to the size of the lens module, automatic calibration and positioning during installation, does not block the lens does not affect the shooting function, that is, stick and use.
