This is a Pocket Walker, which came with the Pokémon HeartGold and SoulSilver games. Functionality has been confirmed. There are scratches on both the front and back. Also, the screw grooves are worn down, making them difficult to turn. It can be opened by hooking a flathead screwdriver into the groove. There are no major scratches that would interfere with gameplay, but there are scratches overall, so please refrain from purchasing if you are concerned about the condition. Instant purchase is welcome.
