The Bresser Junior Microscope set 300x-1200x with case is suitable for children from 8 years. With this transparent microscope you can view prepared subjects that lie between the transparent images. You enlarge your subject 300x, 600x or 1200x and see details that you do not see with the naked eye. This way you can discover in a playful way what the cells of insects and plants look like. The illumination of the microscope is fed with 2 AA batteries.
