Exploring nature is twice as nice with this set of easy-view magnification glasses! Adventurers simply flip the lenses to switch from 2x to 8x magnification for an up-close look at the world. A soft double eyecup makes viewing easy and a built-in LED lights up the night for nocturnal discoveries. Support STEM learning and encourage a lifelong love of science and nature with the GeoSafari Jr. Mighty Magnifiers! Requires 2 AAA batteries (not included).
