Product Material:A full plastic spherical mold with a paper world map on the outside.The base is made of ABS material that can be removed, plus a plastic scale. The text on the map is printed clearly and accurately.
Language: Chinese, English
用途:It is an essential instrument for geography teaching.
A topographic globe is mainly used to reflect the geographical locations, terrain, rivers, mountain ranges, oceans, plateaus, hills, basins, deserts, lakes, and the distribution of ocean currents around the world.
Assembly: Place the support onto the base, then gently turn it until it is firmly fixed.
Use and Protect:
1. When using, you can gently tap the ball to make it rotate freely.
2. Do not allow the ball surface to contact dirty objects or sharp objects.
