About Eraser
An eraser, (also called a rubber outside America, from the material first used) is an article of stationery that is used for removing writing from paper or skin. Erasers have a rubbery consistency and come in a variety of shapes, sizes and colors. Some pencils have an eraser on one end. Less expensive erasers are made from synthetic rubber and synthetic soy-based gum, but more expensive or specialized erasers are vinyl, plastic, or gum-like materials. At first, erasers were made to erase mistakes made with a pencil; later, more abrasive ink erasers were introduced. The term is also used for things that remove writing from chalkboards and whiteboards. Ink erasers are denser, allowing them to erase pen marks.
