Purchased about 5 years ago. Stored in a closet and a clothing case. Used for a few months, but not very often, though this is just my personal feeling. The back has white scuff marks. The surface has some areas where the edges are white. One side is deformed. It appears to be thin, so I think the deformation occurred when putting it on or taking it off. Wiped the entire surface with a disinfectant wipe. Size M, EU36-38, etc. are written on it, but it's difficult to see in the image. I think it's about 23-24cm. Will be sent in simple packaging and delivered to your mailbox. Thank you for your understanding.
