This 4 inch political globe is great for students. It features a colorful and sharp print with continents, oceans, countries and cities indicated. Its clever design allows for full globe rotation at the equator and for equatorial tilt (which even more expensive globes lack). It is perfect for visualizing seasons, day/night, solar and lunar eclipses, and more.
Makes a great gift for a student or a coworker. Use it for education or as a desk toy.
