The Harmony Series Glass Dry Erase Board by Ghent features pale green recycled glass for a calming look in any room. The non-porous surface won't ghost or stain and satin etching on the back side provides vivid contrast. A clear, rear-mounted accessory holder keeps markers and an eraser handy, eliminating the need for a tray. Pre-drilled mounting holes are inset and satin aluminum standoff hangers create a 1 1/4-inch space between the wall and board. 50 year warranty. For best results, mount on light- or medium-colored walls.
