I purchased it for around 4,500 yen last year. It's for display, so there are no noticeable scratches or stains. Includes the instruction manual and will be shipped assembled. Since it is assembled, there should be no missing parts, but there might be a slight possibility. (Since it's assembled, there shouldn't be a situation where you can't build it due to missing parts. If you want the parts perfectly and definitely, please refrain from purchasing as it is a used item.) If you do not need the box during shipping, I will consider some price negotiation. It's first-come, first-served, so please refrain from price negotiations in general.
