Authentic Japanese Pokemon Crystal I've had since I was a teen.

In this auction, you are bidding on the loose game cartridge only. This product does not include the box or the Nintendo 3DS used to verify the game is functioning.

As for shipping, I will be using USPS Ground Advantage (2-5 business days). It will have a code to track shipping. I will also ship the cartridge in a small bubble mailer with the cartridge itself inside of a plastic bag to ensure no moisture damage.

This game is Japanese, not English
It's very likely the save battery is dry, so a new one will have to be installed.
