This is a nostalgic MD player. Since the gum-type battery is not included, its operation has not been confirmed. Operation was confirmed with a AA battery box. Track forward, rewind, and remote control operation were also confirmed. The main unit, cable remote control, and earphones are included. It has aged, so there is some dirt, but it has been cleaned with alcohol. A SONY noise-canceling earphone (last photo) and a confirmation MD are included.
