Another OptiMA® innovation! These are still our very best quality dry erase boards with an imprint of an X/Y axis grid, but they're made on a slightly smaller board size of 32" x 45½" so they can ship by UPS. A traditional 4x4 board is too large to ship by UPS and has to ship via truck, adding the shipping expense to your order. When you're on a tight budget these smaller XY grid boards make perfect sense. These smaller XY boards are an OptiMA® exclusive. No other company can offer them because only OptiMA® makes our boards with the Opti-Print® method. Everyone else has to rely on older technology of making boards using stock fused porcelain; this makes them unable to alter the size of the board or the design of the grid. So we make these in house we can improve our Opti-Print® boards however we want which allows us to offer you a smaller quality XY grid board like these. You get a quality board too with an outstanding writing surface. The boards won't leave behind any type of ghosted image and will erase clean every time. Each board comes with a nice satin anodized aluminum trim, a full-length marker tray and installation hardware. Select from either a magnetic or a slightly less expensive non-magnetic writing surface. Magnetic surfaces will allow you to use magnetic accessories. So keep some money in your budget and purchase our slightly smaller 32" tall x 45½" wide board instead. School purchase orders are gladly accepted.
