The Pencil eraser is an item which is now considered common. They are on the end of almost every American pencil, and can also be bought separately for very cheap prices. However, they should not be considered uninteresting simply because of their popularity.
History
The idea of removing mistakes or other unneeded text from writing is nothing new. In the time of the Roman Empire, wax tablet were used for writing on, and palimpsests were used to remove unwanted text.[1] When Pencils were invented, they proved to be useful items without erasers. It was found that white bread could be used for this purpose, however, so this became the accepted practice until the 1770s when erasure was needed.[2]
