"These magnifying glasses have been used in our programs for years because they have great optics, are a solid quality, don't scratch, and can be used over and over again." - Amy Vanderkooi, Science Educator and Program Manager
These 3x power, 50mm all-glass magnifiers provide crystal-clear optics and are a great learning tool for children of all ages. They are small enough and lightweight enough to fit in backpacks or even pockets. Great for the classroom, goody bags, and exploring.
