Who doesn’t remember that two-tone eraser in their school pencil case? One pink side for erasing pencils, one blue side… for what? Erasing ink? Not really. This stationery accessory actually has several often-overlooked uses. And as you’ll see, its true function is much more practical than you might think.
But what is the blue part of the eraser really for?
A misconception: no, it does not erase ink.
For years, many people believed that the blue part was designed to erase pen marks. The result: holes in the paper and a lot of frustration. It’s a bit like trying to remove a wine stain with sparkling water: the intention is good, but the result is unconvincing. In reality, this blue part was designed for very different uses… but just as interesting , especially for DIY and craft enthusiasts.
