Rubbers are a staple part of any pencil case when you're going back to school - but it turns out we may have all been using them wrong for years. There has been much online debate over how to correctly use a double-coloured eraser (rubber) without ending up with black marks across your piece of paper.

Many people believe the red (or pink) side is for erasing pencil marks, and the blue side is for pen - but it turns out we have been getting it wrong all of this time. Wanting to get to the bottom of it, one Reddit user asked: "If the blue part of an eraser is not for erasing pen marks, then what is it for?"

In response, one user said: "I've always thought that the blue part saves the eraser from being completely gone and you will have something firm to hold on to, to finish the job, without your fingers in the way."

Another user joked: "I thought the pink was for erasing pencil marks, the blue is for erasing pink eraser marks the pink leaves behind."

A third user added: "The blue bit is for removing ink writing, but it always ends up with the paper getting ruined, almost like rubbing sandpaper on paper."

But it turns out we're all wrong as the blue end is intended for coarser paper which would otherwise wear down the softer red side.

A statement from The Pencil Case reads: "You're probably like 95 percent of the population believing that the red bit is for pencil and the blue bit is for pen.

"We have all tried in vain to rub out biro with the blue end, and ended up just destroying the paper.

"The blue end is actually designed for erasing pencil marks on heavy grades of paper or really dark marks.

"Use the red end for light paper and precision erasing, and the blue end for coarse and grainy paper such as artists' sketch pads."

However, throughout the years, many manufacturers have developed blue rubbers that can erase ink from paper. They're usually identified by a small picture of a pen on the rubber.

Commenting on the revelation, one user said: "I came to this conclusion when I was erasing pencil marks on wood with sandpaper. I was like, 'Oh so this is what the abrasive side was for'."

Another user questioned: "People thought it was for erasing ink."
