Eraser
 |
Erasers, also called 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, while others can be temporarily removed and then added. Erasers can be used by rubbing the pencil/pen mark 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 often used for normal papers, while blue erasers are for thick papers. White erasers can be used for all papers. However, this is just a convention, and sometimes this color pattern is not used.[source?] Before the 1770s, people used to use wet bread to clean their mistakes.[2]
