Penvue is an innovative electronic pen that can replace whiteboards

Whiteboards are an easy way to write on a flat surface, and be able to then erase and write over the surface quickly and easily. However, they are not mobile, and over time it can cost money to purchase additional whiteboards and whiteboard markers. The emphasis really being though, whiteboards are not made to move around and typically are stationary, so in a school setting you may have one whiteboard in every classroom.
