I believe this is a rare and unusual item. I purchased it several years ago and have kept it at home since then. Functionality check (DVD/CD playback): It appears to be in good condition with no major scratches. Includes the main unit and AC adapter only. It's a compact size, approximately 14-15cm in both width and height. *Volume can be adjusted by holding down the up/down buttons, fast forward/rewind with the left/right buttons, and skip tracks with the up/down buttons (supplementary information as there is no manual).
