But what is the blue part of the eraser really for?
🔵 The Blue Side: The “Ink Eraser” Myth
Many people were told the blue part was meant for erasing pen ink. Technically, this is partially true — but there’s more to the story.
What the Blue Side Is Actually For:
Erasing pencil marks on heavier or textured paper
The blue part is firmer and grittier, making it better for use on thicker paper, such as:
Sketch pads
Watercolor paper
Cardstock
Removing deeper or darker pencil marks
Its rough texture helps erase marks that the soft side struggles with — like when you’ve pressed too hard with a pencil.
Ink? Kind of, but not really
While the blue side can sometimes fade certain types of ink (especially from erasable pens), it usually damages the paper in the process. That’s why most people ended up with a hole in their homework instead of clean results.
❌ Common Misconception
The belief that the blue side erases ink likely came from marketing, not science. Some packaging even stated it could be used on ink — even though it rarely worked well. Over time, this turned into a widespread myth.
