I found this puzzle among my grandmother's many puzzle boxes. It's still sealed in its original plastic and unopened, although the outer box has some discoloration. This is a rare puzzle by Alexander Chen, made by Apollo-sha, and is no longer sold. It was purchased at the Hankyu Department Store back then. ● Box Size Length: Approximately 30cm, Width: Approximately 40cm, Height: Approximately 6.5cm Please understand that this item has been stored at home for a long time.
