In commemoration of the 90th anniversary of the opening of the Ginza, the first subway line in Japan, we have created a fountain pen ink bottle with symbols/colors corresponding to the nine Tokyo metro train routes as a motif. In addition to the ink bottles, we have included as part of a set an “Edo Metro Picture” and an “Edo Metro Painting,” which are reproductions of a subway map on top of a map of Edo, and created a package as a souvenir for Japanese people and foreigners.
