A whiteboard (also known by the terms markerboard, dry-erase board, dry-wipe board, pen-board, and the misnomer greaseboard) is a name for any glossy, usually white surface for nonpermanent markings. Whiteboards are analogous to chalkboards, allowing rapid marking and erasing of markings on their surface. The popularity of whiteboards increased rapidly in the mid-1990s and they have become a fixture in many offices, meeting rooms, school classrooms, and other work environments.Features-One of a kind functionality-High quality 2d graphics-Excellent Background Music-Excellent Retina Display Support-Excellent Controls-All This for $.99
