This item was used by me when I was in elementary school and has been kept at my parents' house ever since. It's not in perfect condition, but I think it has a nice worn-in feel that vintage lovers would appreciate. I wanted to use it myself, but I've outgrown it, so I'm putting it up for sale. The size is labeled as L, and it's approximately 55cm. It's difficult to measure, so this is just based on how it felt when I wore it. Please only purchase if you can make a judgment based on the description, etc.
