Please read the profile before purchasing. Approximately 12cm in diameter, with some margin of error. This is a deadstock item from an old candy store, taken out of the box for photography. It is unused, but please understand that it is old. The menko cards themselves are relatively clean with no noticeable damage, but the top lid of the outer box has some damage. The illustrations are of Brave Raideen, Kamen Rider Stronger, Ganbare Robocon, and Gorenger. It is probably an unlicensed product, but the cheap illustrations give it a nice, bootleg feel. Feel free to ask if you have any questions.
