Tempered safety glass provides smooth writability with unparalleled erasability. White glass is low iron which greatly reduces the green cast of regular glass, providing a more pure white coloration. Durable steel backing allows the board to accept rare earth magnets. Compatible with any dry erase or wet erase marker, grease pen, etc. and easily cleans without ghosting or staining. Will hang horizontally or vertically. Includes glass accessory tray, set of rare earth magnets, and eraser.
