This was a gift, but I'm selling it because I don't use it. I opened it once to check the contents, but it's unused. It has been stored at home, so I would appreciate your understanding regarding any dirt on the outer box. I intend to offer a price reduction as much as possible, but shipping costs 750 yen, so please refrain from excessive price reduction requests.
