Hankyu Maroon is a Sailor made ink exclusive to the Hankyu Department Store. Hankyu Department Store, which separated from the Hankyu Railway Company in 1947, is a department store who’s main store is located in Osaka. It has further stores nearby and in other cities further away but the only place to buy these inks is from within Osaka, I believe. There are 5 inks under the Hankyu Brand: Wakaba, a light green; Sumire, similar to a light Imperial Purple; Kurikawa, a rich brown; Hanaasagi, a rich dark teal; and this, Maroon.
