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.

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.
