An eraser is a tool used to remove marks made by pencils or pens. It works by physically lifting the graphite or ink particles from the paper. Different types of erasers exist, each designed for specific purposes. Some are made of rubber, while others are made of vinyl or plastic. They come in various shapes and sizes, from small pencil-top erasers to large block erasers. Think of it as an 'undo' button for your drawings or writing.
