Zipped EVA cases offer significant strategic advantages: they are approximately 40-50% lighter than metal cases, reducing international air and ocean shipping costs. Furthermore, EVA does not dent under localized impact, retains its molded memory shape, and the zipper enclosure provides superior dust and splash sealing compared to spring-hinged metal boxes.
Yes. All cleaning spray formulas (such as LC040, LC019, LC304) are non-toxic, alcohol-free/ammonia-free, and safe for all multi-coated lenses (AR, blue-light blocking).
