A mechanical pencil is a type of pencil that uses a replaceable graphite stick, called lead, and a system to push the lead out as it is used. Unlike traditional pencils that need to be sharpened, a mechanical pencil allows for continuous use by pushing a button or twisting the pencil to extend the lead. It typically has a thin tip that provides consistent and accurate lines, making it ideal for detailed drawing, writing, and technical work. Mechanical pencils come in various lead sizes and styles, and they often include an eraser at the end.A mechanical pencil is a type of pencil that uses a replaceable graphite stick, called lead, and a system to push the lead out as it is used.
