This is an Artec "Handmade Telescope, 30x Magnification." It has been opened and temporarily assembled, but all parts are present, and there are no noticeable stains or scratches. I think this would be a good educational tool for understanding the principles and mechanisms of telescopes and lenses. If you purchase multiple items, I will discount the shipping cost accordingly if they can be shipped together, so please feel free to consult in the comments.
