It’s in great condition and complete with box, insert and instructions. The puzzle has marks which raises my suspicions that it has been used but at first glance it looks new boxed. I had one of these in the 80’s and I twisted and stretched the hell out of it trying to solve the puzzle, this one is in very good condition and also is solved so it may be unused and the marks could be age related as it is nearly 40 years old. It includes the instructions The box for its age is in great condition with only minimal edge ware .
