Thank you for viewing. This is a set of Ninja Gaiden 1, 2, and 3. They are not for individual sale. The boxes, instruction manuals, and plastic cases are stored separately and are in relatively good condition, but to prevent any issues, I've listed them as "slightly scratched or dirty." However, there aren't any noticeable scratches or stains. The game cartridges have minor scratches. The instruction manuals are not folded and are in good condition. I've included photos of the boxes, including the tabs, so please take a look. I have only confirmed the initial operation (photos 18, 19, and 20), but the remaining battery life for the backup battery is unknown. I believe it's rare to find these in this condition. I will gradually lower the price if they don't sell, so I won't be able to respond to comments asking for a price reduction. Thank you for your understanding. Please refrain from purchasing if you are overly concerned about minor imperfections.
