This is a set of Surutto KANSAI Rainbow Cards issued by the Osaka Municipal Subway (Osaka Municipal Transportation Bureau), a stored fare system common to private railways in the Kansai region. They are approximately 20 years old. The set includes cards commemorating the 100th anniversary of Osaka Municipal Transportation, as well as cards featuring the main vehicles of each subway line, such as the Midosuji Line 10 series, and route maps from before and after the integration with OTS. They were used normally until the balance reached zero, and then stored in a card holder. However, there are imprints and punch holes on the back. Also, some of the cards have scratches, marks, and peeling of the printing on the surface. Please purchase only if you understand the condition of the cards.
