What is the blue part of the eraser (really) used for? No, it is not used to wipe a pen
The eraser remains a great classic on the list of school supplies. In particular, the very popular double-sided model, pink and blue. The most nostalgic certainly remember it, because it is clearly part of our school memories. Until now, many people thought that the pink material erased pencil marks, while the darker side was more used to remove mistakes written with a pen. But is it true or just a myth? We explain in more detail.

In general, intrigued by this blue rubber material, most students have fun using it at school and at home. Of course, some people have realized that it is not really effective in removing pen marks. However, others are still very stubborn and have a hard time proving that it works. So much so that most of them press so hard that they even tear their notebooks. No more prejudices! This blue part does not have the ability to attack the nib. But what is it really used for? In fact, it has exactly the same purpose as the pink part: it is also used to erase the pencil, with the difference that it is recommended to use it on harder paper, such as a sheet of cardboard or Canson paper, which is used for drawing. In fact, the pink side of the eraser is made of a softer material and is therefore suitable for ordinary paper. While the blue area is stiffer and rougher, it is much more suitable for erasing writing on hard materials where the risk of tearing is low. Plus, you can even use it on walls to remove scribbles from young children.
