[0002] A highlighter pen is a pen used for marking. It uses thicker and lighter ink to cover key areas to mark. Due to the characteristics of the highlighter pen, it can highlight the key points after marking, especially under sunlight, fluorescent lamps, mercury lamps and other lights, it will produce a fluorescent effect, making it look more conspicuous and will not cover the text;

[0003] However, when writing with an existing fluorescent pen, the pen tip does not absorb ink smoothly, which easily leads to poor ink supply and affects the writing effect. When the ink of the fluorescent pen is used up, it is inconvenient to replace and refill the ink, which affects the service life of the fluorescent pen. In addition, when writing with a fluorescent pen, the ink writing is easily smudged to other parts of the medium surface. After the ink is smudged and diffused, the writing becomes blurred, and the purpose of highlighting the mark is not achieved.
