Admit it: you’ve tried too. As a child, armed with your famous pink and blue eraser, you frantically erased a word with a pen… only to see the paper tear up before your eyes. That small blue half, destined to “erase the ink”, has shattered the dreams of many schoolchildren.
But then, what is the blue part really for? Was it just a marketing strategy or a misunderstood professional tool? The truth is much more practical and a little nostalgic.
No, it was never designed to erase ink.
This is the most persistent myth in our school cases. Contrary to popular belief, the blue part of the eraser was never designed to remove ink from the pen.
In reality, it all comes down to its composition: it contains abrasive particles, similar to pumice. In short, it is a kind of mini, very fine sandpaper designed for harder surfaces. On a regular sheet of paper, these grains are too abrasive and end up tearing it.
Their real playing field? Resistant surfaces.
Blue Eraser is a little champion of DIY projects, drawing, and creative hobbies. Here we tell you about their true hidden talents:
Pencil marks on raw wood
Before drilling or assembling furniture, we usually draw guides with a pencil. A quick tap with a blue eraser, and it’s gone! It removes graphite without damaging the wood, especially if it is not varnished.
Marks on walls or plaster
When writing down a measurement or the position of the frame directly on the wall, the blue eraser can make the marks disappear, as long as you do it carefully.
Thick papers and cardboard Scrapbooking and drawing enthusiasts
know the problem: pencil marks leave deep marks on cardboard. A blue eraser is perfect for correcting them without smudging or tearing them.
