Sega Mark 3 Game Cartridge Shell [Transparent Blue]

These are brand new Sega Mark 3 game cartridge shells. They are made in the USA and are identical to the originals. They are based off the first generation variant of these shells which are compatible with the SG1000/SC3000 and feature 2 internal tabs instead of four like the later version. I own the mold and can make other colors, just ask.
