The Travelscope is a valuable tool for exploring anything from coins and stamps to the hidden world of nature. This 20x stereo microscope is a great tool for discovering more about the world in which we live. Look at rock formations, insect habitats, or sand from the beach. Because it is battery operated and light-weight it can go almost anywhere. A great field trip microscope. The unit is 8” x 2.5” x 5” and requires 2 “AA” batteries (not included). Ages: 7+
