Test Cartridge with Crystal Clear Shell

I custom-craft these by making a mold from an original cartridge, then hand-cast them using colored clear resins.

These are outfitted with the Game Boy Test cartridge for testing the functions of your Game Boy DMG, Game Boy Pocket, Game Boy Color, and Game Boy Light. They will also work on the Game Boy Advance, Game Boy Advance SP, and Game Boy Micro, but this cartridge cannot test the shoulder buttons on them.
