foosball erasers

The school has started and the lectures can be so boring sometimes. Why not play foosball while the teacher boringly explains the calculus or some boring theory of some Faulkner story. It’s foosball time! Yes, you can play all by yourself or with your buddy. Just slide it onto a pencil and voila, you are all set. If the teacher comes just pretend you are erasing something – after all they are fully functional erasers.
