A writing instrument which can be used as a broad line marking instrument or as a fine line writing pen. The instrument has a marking nib (60) and a fine line writing nib (35) located at the same end of the instrument. The fine line writing nib is retractable and can be activated by the press of a button (45). When the fine line writing nib is retracted the instrument can be used as a conventional permanent marker or highlighting marker depending upon the type of ink employed. When the fine writing nib is activated, it protrudes through the marking nib and automatically locks into writing position. Only one protective cap (90) is needed to protect the nibs when the instrument is in nonuse. |
