Purchased about 20 years ago for around 20,000 yen. Size: 24.5cm There is deterioration and damage due to aging. No box. I haven't worn them much in the last 3 years because I was transferred to a department where the work clothes are work uniforms. Model number is unknown. Please judge the condition from the photos and purchase only if you are interested. Shipping is planned via Rakuraku Mercari Bin, but may be changed to Yu-Yu Mercari Bin without notice. (Please cooperate with Eco Mercari as much as possible.) REGAL Instant purchase without comment is OK.
