Abstract
A marking pen is fabricated so that a twin-inserted head is inserted separately into different colored ink tubes, when the ink flows from the ink tubes to the head of the pen, the colors 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 and create multi-color changes to the work produced without going through a color spray finishing process.
