Since the time that Anton Van Leeuwenhoek first gave us a glimpse of those unseen worlds through his first microscope around 1668, our fascination with microscopes has held us in its grasp. From the young to the older, the chance to see and explore everyday things and lost treasures that surround us has sparked new excitement with the amazing details that were previously hidden from our view. The Microscope Explorer Kit is an especially valuable tool to explore anything from coins and stamps to the hidden world in nature — all with incredible clarity. This kit includes a high-quality battery operated 20X stereo microscope with top-grade optics, adjustable interpupillary eye piece, LED light source, sturdy plastic base and more. Also included is a cleaning brush, tweezers and three uncleaned ancient coins, approximately 1500 years old, to start your exploring. (The size, condition and type of coins will vary with each kit.) The microscope requires 2 AA batteries (not included).
