The outer box, instruction manual, and Pokéwalker are all included. The game data and Pokéwalker information have all been reset, and functionality has been confirmed. Also, the Pokéwalker's battery has been replaced with a new one, so you can use it right away. The Pokéwalker shows signs of use, such as scratches on the screen, so please only purchase if you understand this. Due to aging, the box also has scratches, so please refrain from purchasing if you are looking for a pristine item or are overly concerned about condition.
