Showa Retro Barrel-Shaped Puzzle Game Scorpion 10 Unopened, with case. This is similar to Ten Billion, which was released by Nintendo in 1980, but this one has "Scorpion 10" written on the package. Although it is unopened, it is over 40 years old, so there are scratches and dirt on the case, as well as peeling of the package seal. *See photos 5 and 6. Please purchase with the understanding of the above.
