Tiny polishing marks on lens edge and subtle brushed texture on shell are standard production craftsmanship, not product defects. - Material Wear & Tear : Optical lens will form fog stains after long contact with fingerprints and oil, and frequent wiping may scratch the lens. Metal shell may oxidize and darken under moisture or sweat, and the hinge may loosen after repeated folding. These are normal wear, not covered by free after-sales service. - Usage & Precision Note : 30X magnification requires standard viewing distance, eyesight differences will lead to different definition experience.
