Pencil and Ink eraser


The white side of this eraser is a regular graphite eraser, the other grey side is micro-abrasive and will physically take off the very top layer of the paper, removing any permanent markings, such as ballpoint or other permanent inks. 

Something of a by gone era of typewriters this eraser is still very useful for corrections of official documents or where forgery is required. 

Probably not recommended for use with historical documents where preservation is a concern.
