Input: I wanted to be really excited about this whiteboard mat. But when the order arrived there were no pens or eraser like it was advertised. The tube the mat arrived in was not sealed on both sides and there was no sign of the eraser or pens in the box. My guess is the pens and such fell out before it even got into the shipping box. Hopefully Expo pens don't stain the mat I guess
