No Pay No Gain
No Pay No Gain

When the teacher has finished a lesson, it will be very tired if he need to erase the entire blackboard by using a small eraser on his own. But, by using this handy tool, he can erase the whole blackboard with just one push. If he just want to erase a small area, he can simply take an eraser down and use it, simple as it sounds.
