Erasers are small, rubber-like material used for erasing or correcting pencil marks. Most erasers are made of a combination of rubber, pumice, latex, and oil. They come in many shapes and sizes, from small, hand-held erasers to larger, stationary erasers. The most common use of erasers is to remove pencil marks from paper. Erasers are also used to erase pencil marks from cloth, wood, and other non-paper items. Some erasers can also remove other types of markings, such as ink and permanent marker.
