I haven't confirmed the operation because there's no power cable. The dedicated case shows noticeable dirt, but the main unit has no noticeable scratches or stains. Dedicated touch pen included. This is a SHARP Brain PW-GC590 electronic dictionary. Based on the images, the main unit appears to be in relatively good condition with no significant scratches or stains. It comes with a dedicated case, making it convenient for carrying around.
