I believe this is a prize or giveaway item from Jump. It seems to be a collaboration between Shueisha and Takara. "Hagaki Senshi Jump-dan Jinsei Game: Dobunezumi no Ballad Edition 0" The package size is approximately 18.5cm x 10.5cm. The board is folded in four and stored inside the box. When unfolded, it measures approximately 37cm x 21cm. The accessories are somewhat old, so I cannot guarantee that everything is complete, but I think it probably is. If you have any questions, please feel free to ask in the comments. Please consider this item only if you understand that it is a used, retro, and junk item.
