These are prescription glasses, so please only use the frames. Created at a JINS store at the end of February 2022. As a spare, I made another pair on the same day, so I used them on a weekly basis. The usage period was about half a year. I am giving these away because I have made new glasses and no longer need them. The frames are in beautiful condition with no noticeable dirt or scratches. I hope you will find them useful. * I will ship them in a JINS red glasses case.
