Thank you for viewing. Pokemon Blue Game Boy cartridge. It's been socketed, and can be opened and closed with a Phillips head screwdriver, so anyone can easily replace the battery. 〇 Condition It works well, and I recently cleared it three times. It's a game from 1996, so there is some deterioration due to age, and the condition is listed as "Slightly scratched or dirty." Please check the appearance in the photos. This is a used item, so please refrain from purchasing if you are sensitive to such things. 〇 Shipping I try to ship the same day. I will pack it carefully using materials I have at home. Please feel free to contact me if you have any other questions.
