Unused item. Model number unknown. The color under fluorescent light is the color in the second photo. Size 11, so I'm listing it as a size M. Waterproof packaging only. There is a possibility of changing between Yu-Yu and Raku-Raku shipping. Only for those who understand that this is a used item. Please refrain from claims or returns due to amateur inspection and storage. If you would like to offer a lower price, please include your desired amount in your comment. Please refrain from unreasonable price reduction comments. There are periods when shipping is not possible during the year-end and New Year holidays.
