In spite of the upgrading of the production standard of arts and advertising work, a pen used for marking can only draw out a monocolor. As a remedy, in the present invention the interior end of a marking pen is fabricated in such a way that a twin-inserted head or more is inserted separately into different colored ink tube, so that when the ink flows from the ink tube to the head of the pen, the color will mix naturally in the area adjacent to the middle of the bottom end on the head of the pen, so as to produce a gradually-layered color effect to further create multi-color changes to the advertizing work produced without going through a color spray finishing process. The penholder is made of elastic material. By pressing one's fingers against the penholder the ink contained therein will rapidly flow to the head of the pen, and further pass the two through holes on two connic bodies set on the top end of the head of the pen to make direct access to the bottom end until reaching the two ends of the head of the pen, to ultimately enhance the various color at the two ends and rapidly recover the gradually-layered color effect.
