For Grades 5-3 EL-90/EL-87 Price: ¥2300 + tax This is an old piece of sheet music, so there is some yellowing, but it is still usable. A floppy disk is included, but I no longer have an Electone, so I haven't been able to confirm if it works. Please note that we cannot guarantee or accept returns if the disk does not work on the buyer's model.
