Official Nintendo Game Boy Cleaning Kit Cartridge

Found this old school Nintendo Game Boy cleaning kit cartridge. It's the official one from back in the day, meant to keep your handheld and games running smooth by cleaning the contacts. It's in decent shape for its age, just the cartridge itself here. Cool little piece of gaming history if you're still rocking the original DMG or just like collecting the weird accessories. Label is still intact and looks pretty good.
