This is a set of the above three items.

Please note that we do not sell them separately.

These are opened items.
The outer box has some damage and dirt from storage, but the main unit does not appear to have any noticeable damage to the naked eye, so this is the condition listed.

Please research the details yourself on the internet or elsewhere.

They were stored in a dark place in the condition shown in the photos.
We ask that only those who understand that this is a used item that has been in someone else's possession purchase it.

We would appreciate it if you refrain from requesting additional support.

The photos show everything included.
