SONY's PocketStation is a handheld device that allows you to save game data and enjoy mini-games. - Brand: SONY - Model Name: PocketStation - Included Items: Instruction manual, strap - Model Number: SCPH-4000 The box has been opened, but the device has not been used. As this is a very old item, the box and bag have scratches and stains. The bag is unopened, so it is unknown if it functions properly. I will sell it to someone who understands this.
