This is an official Nintendo Game Boy communication cable (model number: DMG-04). It has been stored at home for a long time. I am unable to test the communication function with my current setup, so I am selling it as untested and in its current condition. Due to its age, there may be scratches and stains from wear and tear. Please check the images and only purchase if you agree. Please refrain from purchasing if you are sensitive to these issues. *Returns are not accepted to prevent product substitution.*
