Eraser
 |
Erasers or rubbers, are tools made from rubber[1] or vinyl and are used to get rid of marks made from pencils, or some types of pens. Some erasers may be be attached to a pencil, or could be bought to be shoved on a top of a pencil. Erasers can be used by rubbing the mistake and it will slowly clear away. All erasers will produce some dust called debris. There are some erasers which are very soft and can erase easily. Pink erasers are for normal papers. Blue erasers are for thick papers. White erasers are for all papers.[source?] Before the 1770s, people used to use wet bread to clean their mistakes.[2]
