POSTITNOTE
Post-it note
A Post-it note is a piece of paper stationery with a re-adherable strip of adhesive on the back, designed for temporarily attaching notes to documents and other surfaces. Although now available in a wide range of colors, shapes, and sizes, Post-it notes are most commonly a square, canary yellow in color. A unique low-tack adhesive allows the notes to be easily attached and removed without leaving residue.The above text is a snippet from Wikipedia: Post-it note
