Do you remember this old maroon-blue colored pen eraser (rubbers) you used during your childhood?
Yes, the same pen eraser, which the children of nineties are familiar with. A majority of us feel that the Maroon color part is simply used in order to erase the mistakes that are committed with a pencil, while the colored one was meant to fix the errors made up with a pen. However, this is one of the usual notions about the same, but not many would know that this is a common conjecture we had in our childhood. The fact is the blue color rubber was not meant to fix the mistakes committed by your pen, okay, let’s check it what it really was meant for?
