invention · office supplies · adhesive

Accidental Discovery. A scientist at 3M stumbled upon the special glue used in Post-it notes by accident, and it turned out to be perfect for sticking and unsticking things.

Started as Yellow. Post-it notes began as small yellow squares, but now they come in at least 28 different colors, plus tons of different shapes and sizes.

Magic Adhesive. The glue on Post-it notes is low-tack, which means it's weak enough to peel off without ripping your paper or leaving sticky gunk behind.

Award-winning Design. Post-it notes have won several awards for being smart inventions and looking great, proving that sometimes the simplest ideas are the best ones.
