Third-copy products are low-grade imitation items that loosely copy the style of original branded products but with minimal attention to detail or quality. In the difference between the first copy and the original, originals are brand-made and certified, while copies are imitations; among these, third copies sit at the lowest level. In first-copy vs. original products, first copies try to closely match the design, but third-copy products use cheaper materials, rough finishing, and basic manufacturing. When comparing original vs first-copy sunglasses, first copies may still look similar at a glance, but third-copy sunglasses usually have poor lens clarity, weak hinges, and no real UV protection. This real vs. imitation products comparison makes it clear that third-copy products are far from genuine and are mainly sold for their low price rather than durability or safety.
