Designed by a mother of two preschoolers, the GeoSafari® Jr. My First Microscope puts the world of the close-up in the hands of small children! This fully functional microscope is a real tool. With two extra-large eyepieces and a chunky, kid-sized focusing knob, kids can see a magnified hidden world with ease. A bright LED with easy push-button action lights up details for even more discoveries. Requires 3 AAA batteries.
