How it's used
Often called a "hard eraser" in English, this tool is specifically designed for abrasive removal of ink marks from thick paper. It is significantly more abrasive than a standard rubber, so using it on thin or delicate paper will likely tear the page. Many people now use correction fluid or tape instead, making this a somewhat old-school stationery item.

Common mistake
Do not confuse this with a standard eraser, which is called 擦膠. Using a 沙膠 on normal notebook paper will almost certainly damage the surface.
