I purchased these a few years ago and used them for a short period, but they have been stored at home since then. They have prescription lenses in them. Please replace them as needed. The original glasses case from when I bought them is also included as a bonus. Please refrain from purchasing if you are concerned about minor scratches or signs of use, as they have been used once. JINS CLASSIC Slim Acetate LCF-18A-006 Color: Brown Demi 486 ↓ From the official website: A modern classic series that incorporates classic elements into a trendy slim frame. This is a cassette that pursues a slim and easy-to-wear shape, and balances delicacy and classic taste. The frame material uses the new "compressed acetate" technology, which achieves a thinness that cannot be achieved with ordinary acetate frames, while maintaining the same fabric strength as ordinary acetate. The design incorporates elements of color direction, such as vintage glass and marble patterns, and is finished with a modern atmosphere that arranges the good old style in a contemporary way. This frame is recommended as the next pair for everyday use, even for those who already have basic classic glasses.
