An eraser or rubber is an article of stationery that is used for removing pencil and sometimes pen writings. Erasers have a rubbery consistency and are often white or pink, although modern materials allow them to be made in any color. Many pencils are equipped with an eraser on one end. Typical erasers are made from synthetic rubber, but more expensive or specialized erasers can also contain vinyl, plastic, or gum-like materials. Other cheaper erasers can be made out of synthetic soy-based gum.

Used by school and college going students, erasers are used in addition to the common pencil erasers and some special type of erasers such as typewriter print erasers, ink erasers, etc., which are used in offices and other establishments.
