How Millions of Erasers Are Made | From Soft Rubber to a Clean Page

One rub, and the pencil mark is completely gone — but have you ever seen how an eraser is actually made? From soft raw rubber and fine fillers to giant mixing mills, heated presses that shape thousands of erasers at once, sharp cutting blades, colour sorting, and the hidden factory tests that decide whether an eraser leaves a clean page or a dirty grey smudge, this is the full journey of an eraser, from raw rubber to the school bag in front of you. Watch rubber become colour, colour become erasers, and erasers become the millions of clean pages the world writes on every year.
