This is a Pokéwalker. It is unused, so I haven't confirmed its operation. The insulation sheet is still in place. It has been stored at home for a long time. *The instruction manual will be included when shipped. As you can see in the images, there is a case, but there is no software! I will send everything in the images, but please note that there is no software! Please only purchase if you understand that it has been stored at home. Pokémon HeartGold
