What is the real use of the blue part?
Contrary to popular belief, the blue side is well intended to erase the pencil, but on specific surfaces. It's harder and abrasive, making it ideal for:
Thick and rough papers, like Canson paper used for drawing.
Cardboard and other rigid surfaces, where the pencil adheres more.
Removing marks on walls, including doodling by children.
The pink side, on the other hand, is softer and suitable for classic papers, such as those of notebooks and filing sheets.
What the specialists are saying
The manufacturers themselves confirm that the blue part was never designed for ink. Its abrasiveness simply makes it possible to erase more deeply on hard surfaces.
Some blue gums may attenuate light inks on thick paper, but they do not completely erase them.
Conclusion: Ideas that have been received.
If you were one of those who thought the blue gum was erasing the pen, you're not alone. But now that the truth is restored, no more need to press as a forced one on your leaves. Use the bright side in the right place, and your pencil mistakes will go away without worry.
