A Sticky note or Post-it note is a piece of 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 3-inch (76 mm) square, canary yellow in color. A unique low-tack adhesive allows the notes to be easily attached and removed without leaving marks or residue, unless used on white boards. I found one funny sticky notes on LCD where the person also noted that sticky notes also they have to buy… Looks funny lol.
There are smaller sticky notes on the right under the screen 🙂
