The car body was adopted for the first time in Keisei as a lightweight all-stainless structure that was being put into practical use. Like the 3500 series, an orange band was placed above and below the front and side windows of the train, but from September 1992 to March 1993, it was formed in 3608 - 3638 formation bands of side window tops, changed from orange to blue. In September 1993, set 3648 changed the front and side window lower zone from orange to red and blue, and the change of the whole organization was completed by June 1995. Initially, the band of the side door part was omitted, but the band was affixed at the time of paint change. On the side door closing part there is a plate attached, with the notation of the writing style Keisei logo. In March 2001, along with the introduction of the Kei Group's CI, the K'SEI GROUP logo was affixed to all sides of all vehicles.
