This listing is for a VINTAGE SONY MINIDISC WALKMAN RECORDER MODEL MZ-R91, well preserved, looks close to new. The paper box that you see in the photos is not included, only the player, the paper box is for another model mz-r90 that I was making photos of at the same time. Playback and recording was tested and item works fine. Included is only the player, no paper box but will be packed in a small shipping box. How to power the player: No battery is included, the old battery was left inside the player and had leaked so I had to throw it away and clean the contacts so I can test it. The battery type it uses is the common flat 1.2v gumstick battery which can be purchased easily brand new for few dollars. Listing #B08071105071313
