Product Details: Game Boy Color Pokémon Crystal Version cartridge only. Tested and working. New battery installed. Maintained. Beautiful condition. The only included item is the game cartridge. There is no noticeable damage to the label. The exterior is also in good condition. I believe it is a beautiful item. Operation confirmed. I replaced the battery, so you should be able to use it comfortably for a while. Save data confirmed. I plan to pack it with bubble wrap and ship it via Nekopos. Thank you for your consideration.
