If you’re ever stuck somewhere filling out endless paperwork or doing a test, you have to find someway to keep yourself entertained. Be it staring off into space thinking about anything but the task at hand or playing with these erasers. They have pull back action so they fly across the page just like a normal pull back car would, except these double as erasers. It’s probably not wise to start making car sound effects in the middle of an important test though. People tend to frown on that. You can purchase a set of four of these for $3.50 from Pop Deluxe.
