Large dry erase Cartesian graph boards from our very own OptiMA Graphics division are available in either a magnetic or a non-magnetic format. We are the factory so we can offer them to you for less.
If you select magnetic receptive that means that you will be able to use all kinds of magnetic accessories with your board. The more economical non-magnetic boards will save you some money. They have the exact same awesome dry erase writing surface, frame, tray and print. The only difference is that magnets will not stick to them.
These are large 4' x 4' dry erase boards beautifully printed with X & Y axis lines and grid. These grid boards are created with the Opti-Print method which means that the print is completely protected and will last for the life of the board.
The grid pattern is 1" with a line thickness of 1/32". The X & Y axis lines are 1/8" thick and printed in bold black. The boards have a satin anodized aluminum and there is a full-length shelf type marker tray.
These Opti-Print XY graph coordinate boards are the perfect teaching tool. Our dry erase surface resists ghosting and erases cleanly every time with proper care and maintenance. The boards are too large and heavy to ship by UPS so they must ship by truck. As always with OptiMA Inc., school purchase orders are gladly accepted.
