Sticky notes, also known as Post-it Notes, are small, adhesive-backed pieces of paper used for temporarily attaching notes to documents and other surfaces. They typically come in a variety of colors, shapes, and sizes, allowing users to organize information in a visually appealing and convenient way. With their ability to stick to most surfaces and be easily removed without leaving residue, sticky notes are a popular tool for jotting down reminders, marking pages in books, brainstorming ideas, and collaborating on projects. Their versatility and portability make them an indispensable tool for both personal and professional use.
