Dry Erase Polar Coordinate Axis Magnet, Black and White Polar Grid

This large, reusable dry erase polar coordinate magnet is an excellent tool for classroom instruction, providing a convenient way to display a clear graph on any smooth steel surface, such as a magnetic classroom whiteboard or chalkboard. The robust construction process, manufactured in the USA, involves printing the polar coordinate grid onto heavy duty white vinyl, then protecting that print with our exclusive clear dry erase writing surface, and finally laminating the entire assembly onto a heavy gauge magnetic sheet for secure adhesion. The magnet ships rolled in a corrugated storage tube and is easily rolled out for immediate use and then rolled back up (print facing out) for safe, long term storage between lesson plans.
