A notepad is a collection of sheets of paper bound together, often used for writing notes, lists, or sketches. They come in various sizes and formats, including lined, blank, or grid paper, catering to different needs. Notepads are commonly used in schools, offices, and homes for jotting down ideas or reminders. Many notepads are portable, making them easy to carry in bags or backpacks. Some notepads are designed for specific purposes, such as legal pads for legal notes or sketch pads for artists. They can be made from recycled materials, promoting environmental sustainability.
