I received this as a gift around December 2025. After finishing the cookies, I kept the container because I felt it would be a waste to throw it away, but it seems I won't have a chance to use it, so I'm listing it for sale. Shipping via Yu-Packet Plus will cost 520 yen (455 yen for shipping, 65 yen for the dedicated box), and shipping via non-standard mail is expected to be 390 yen. If you choose non-standard mail, I can lower the price to 555 yen, so please comment before purchasing. After washing it thoroughly, I tried to remove cookie crumbs from the corners with a brush, but there may be some remaining. This is a used item, so I would appreciate it if someone who understands this would purchase it.
