Contents: I apologize, but this is only the main unit. Operation confirmed. Condition: Overall, there are signs of use and scratches. There are no major scratches or dents. (Regarding the front, the camera's exposure has been set to "very strong" to clearly show the condition, so it may appear more noticeable than it is.) Please consider the appearance from the front to be as shown in the first and second photos.
