This is a Pokémon Pocket Monster Pokéwalker. The battery has been replaced and the power has been confirmed to turn on. I do not have the DS software, so I have not confirmed the connection with the software. Thank you for your understanding. This item has been stored at home for a long time. I think it's in relatively good condition as I have kept it for a long time. Please forgive me if I have overlooked anything. Please purchase with the understanding that this is a used item. - Model: Pokémon training game - Color: Red and White - Display: LCD screen - Brand: Nintendo - Function: Training and battle functions Thank you for viewing.
