This is an Open Box item where the previous owner literally opened the boxes and decided this was not the hobby for him.  Everything is new - right down to the undisturbed original tissue paper wrapping the OTA.  This isn't just "like new"; it is new. 
However, because it is an open box item, we cannot sell it as new.  We are therefore passing the savings along to you.
