Standard whiteboards are very large and wide, the Maven Slim Whiteboard's thin design allows you to mount it in more places. Perfect for errand or to-do lists in college dorm rooms or small office walls between doors. Also: There are no markers, no solutions and no erasers included with this whiteboard. It is the slim White Board, tray and screws only. Note to buyers: The white boards come with a clear protective cover film that should be removed before use. We apply this to limit any surface scratching when shipping. If there are any problems, please reach out to us and we will make it right. Thank you!
