Erasers are small tools used to remove pencil marks from paper. They are typically made from rubber, vinyl, or a combination of materials. Erasers work by lifting graphite off the paper's surface, allowing for corrections in writing or drawing. They come in various shapes and sizes, including rectangular, cylindrical, and novelty designs. In addition to traditional pencil erasers, there are also specialized types, such as ink erasers for removing ink marks and kneaded erasers that can be shaped for precise erasing. Many people use erasers in schools, offices, and art studios to ensure clean and accurate work.
