How it's used

Refers specifically to markers or felt-tip pens that use water-based ink, which distinguishes them from oil-based permanent markers. It is the standard term for whiteboard markers used in classrooms and offices. Because the ink is volatile, the habit of capping the pen immediately after use is essential to prevent it from drying out.

Common mistake

Do not confuse this with fountain pens or ballpoint pens, as the ink composition and writing experience are completely different. Also, ensure you do not use this term for permanent markers, which are usually referred to as 油性筆.
