Up for buy it now is the IBM PC Convertible shown. It is extremely rare in that it is still factory sealed in plastic This being the case, it has not actually been tested as that would require it to be opened. It does not include the display or power adapter which you'd need to actually use the unit and the display must have been originally packaged separately.
Since it is not a complete nor tested unit, it is sold for parts/as with no returns is and it wouldn't make sense to accept returns once the seal has been opened as it'd no longer be sealed.
USA shipping is included. Thanks for looking and please ask any questions you may have!
