This is a Family Computer Disk System and its dedicated AC adapter. I believe it's new and unused, but I can't be certain since it's an old item. The box and bags show some deterioration, but the main unit appears to be free of noticeable scratches or stains. I haven't tested its functionality as I don't want to disturb its current condition. Please be aware that this item has been stored at home for a long time and is not perfect. Please also note that the functionality hasn't been confirmed. No returns accepted. Please feel free to ask any questions in the comments.
