National Geographic Microscope Set 300x 600x, and 1200x Magnification

National Geographic Microscope Set 300x 600x, and 1200x Magnification. I do believe all of the pieces are there except for maybe 1 or 2 glass slides. This is in excellent condition - I would say it hasn't been used, but not sure. I have included a picture that lists all of the items in the case. Comes from a clean and smoke free home.
