Thank you for viewing. This is a Pokéwalker that came with the Nintendo DS game "Pokémon HeartGold." I already sold the game software, so this is a listing for the Pokéwalker only. I bought it new when it was released, but I barely remember using it, so I'm considering it as unused (or close to it). The insulation sheet is not included. Please purchase only if you understand and accept the above. I will pack it with bubble wrap and ship it via Yu-Yu Mercari Mail (Yu-Packet Post Mini).
