Unopened. Approximately 23cm. I've generally marked the item as "Slightly Damaged or Dirty." I only mark it as "Damaged or Dirty" if there's noticeable damage, deterioration, or if it's an item from the past. I plan to ship via Mercari delivery, but I won't specifically notify you if I change the shipping method. I have a large surplus of cardboard boxes purchased from online shops, so I will reuse boxes with the shop's logo or that are slightly dirty. Please refrain from purchasing if this concerns you. The colors may appear different due to the photography equipment. Everything in the images is included. I do not respond to negotiations made through comments. I have a cat, so it's unavoidable that cat hair may be present. Please refrain from purchasing if you are concerned about this.
