Whiteyboard, Like IdeaPaint, But Portable & Inexpensive
"WhiteyBoard was born in 2010 to attack one major problem; Heavy, Expensive Dry Erase Boards. With our team of chemists, we came up with an ultra inexpensive white board that sticks on to any wall, weighs less than 2 pounds and gets you working in seconds. No installation, no heavy lifting, no breaking the bank. WhiteyBoard is already being used in hundreds of offices, classrooms, and kids rooms around the US."
