A two-car connected wind-up model of the "2000 series," the symbol of the Sapporo Municipal Subway, which debuted when the Namboku Line opened in 1971. This is a collector's item, a limited-edition original product of the corporation, and is now difficult to obtain. • Recreates a historical vehicle: This model lovingly recreates the unique form of the 2000 series, which adopted the globally rare "center guide rail + rubber tire system," in an adorable size. Used, opened, and stored at home. Returns and cancellations are not accepted.
