Sega's Classic Cartridge based handheld console. This one has had the works done to it, recapped, new screen, new transparent shell, CleanAmp GG soundboard by Retro Six, and USB C charge socket. 

Console only in Excellent, fully tested condition. Screen quality is amazing compared to an original Game Gear console. Has an original metal stand at the rear, some slight crack marks around where it fits into the casing - but not an issue.  Looks barely used, 10/10. Includes both battery covers.
