12 Game Boy game cartridges. 5 of them are Game Boy Color games. Since I don't have the console, I haven't confirmed they work. There is writing in marker, stickers, scratches, and dirt. Please check the images and understand the condition before purchasing. Regarding Pocket Family GB, the button battery compartment is unopened, so there is a possibility of battery leakage. No refunds or exchanges are possible even if they don't work.
