Innovative whiteboard surface uses nanotechnology to prevent ink from penetrating the surface. A hydrophobic, Nano-Clean surface coating delivers exceptional ghost-resistance and stain-resistance with superior erasability so you enjoy top-notch performance in extremely heavy-use environments. Nanoparticles fill voids on the board surface to prevent ink from staining or ghosting. Whiteboard surface is magnetic to offer equal functionality for smooth writing and posting of printed materials. Board surface is recessed from the black aluminum frame for a fresh, clean look. The whiteboard can be mounted vertically or horizontally with included Z-bracket mounting hardware. The board also includes a marker tray and one Quartet dry-erase marker.Innovative whiteboard surface uses nanotechnology to prevent ink from penetrating the surface.
