OptiMA® offers dry erase polar grid boards that excel in two significant ways, distinguishing us from our competitors. Firstly, we provide the option of both magnetic and non-magnetic polar coordinate dry erase boards, recognizing that not everyone needs magnetic features. This allows you to choose the format that best suits your needs without paying extra for unnecessary features. Secondly, we offer a more compact board size of 32" x 45.5", designed for UPS oversized shipping, providing a cost-effective alternative to large truck deliveries. All our coordinate grid boards are made using our exclusive OptiPrint® method, ensuring crisp, durable images that are protected beneath a clear dry erase surface. With proper maintenance, this surface will last for years, erasing cleanly without leaving any ghosting marks.
