These are glasses from JINS. I bought several pairs a few years ago for home use, each costing 5,000 yen. The cases are from JINS. They were only used at home, so they are in clean condition with no noticeable stains. Individual purchases are also welcome, but since they will be shipped via Yu-Packet Plus, the price for one item will be 900 yen. The lenses will need to be replaced as the vision correction varies from person to person. Thank you for your understanding regarding used items.
