Opera glasses (sports glasses) purchased in 2012 during a world ballet performance. They fold up compactly, making them convenient to carry. Used only once on the day of the performance and stored at home. While there are no noticeable scratches or stains, the plastic outer box has a retro feel due to the passage of time. The main body is in beautiful condition. Please understand that this is a used item before purchasing. ※ Size: 6.5cm x 11cm x 1cm (folded), measured by a layman.
