The 3 x 4' white Visionary Move Mobile Magnetic Glass Whiteboard from Balt features a double-sided magnetic smooth glass surface. It is height adjustable to 60.5 or 72.8" for viewing. The design of this board provides twice the functionality of a wall-mounted board since it can be rolled on its four dual-wheel lockable casters. This whiteboard features a wide base for stability. The smooth finish accepts dry erase, wet erase, and chalk markers and accepts rare earth magnets. The frame and trim are made with silver powder-coated steel.
