OptiMA® extra large 4' tall x 8' wide, magnetic dry erase boards with horizontal lines created with the OptiPrint® method. The horizontal lines are permanently printed onto the board with either 1" or 2" between each line. The lines are then covered with an exclusive clear dry erase material protecting the lines indefinitely. We promise that they won't rub or flake off. You can select from 1" or 2" tall rows. You can also select your rows to be solid white or select rows that alternate from a very light gray shading in one row to solid white in the next. These alternating colored rows are called variegated. Many customers prefer variegated or alternating colored rows feeling that the rows are easier to follow when tracking across the board. The boards have permanent horizontal printed lines onto the writing surface. Using those permanent lines you can create your own extra-large changeable magnetic planning boards by simply adding the vertical lines to make your columns. The 4' tall x 8' wide marker boards come with a really nice aluminum trim and a full-length, marker tray. 4' x 8' magnetic lined dry erase boards cannot ship by UPS due to their size. They are too large and must ship by truck. All sizes are made to order with a lead-time of about 3-5 working days to ship from the factory. Tip: It is not recommended to clean these boards with anything containing ammonia which is found in most glass cleaners.
