A whiteboard sheet that you can stick on the wall and use as a whiteboard. An eraser and a dry erase pen are included, with original manual and box. The stickers that came with it are unused. The size of the sheet is 36 inches by 23.5 inches (roughly a poster size). It's very light so you can take it anywhere for group meetings, etc.
