[0002] A colored marker pen is a pen that can be used to write marks or logos on one or more materials such as paper, wood, metal, plastic and enamel ceramics. Colored marker pens are divided into oily and water-based. Water-based colored marker pens can be used to write on smooth surfaces or whiteboards and can be wiped off with a rag, while the content written by oily colored marker pens is not easy to erase. The utility model patent with application number: CN202220151538.2 discloses a combined leak-proof watercolor pen, including a device body, which includes a shell, a pen cap, a tail cover, a connector and an ink sac. One side of the end of the shell is connected to one side of the outer wall of the tail cover by a thread, and a sealing gasket is sleeved at the connection between the tail cover and the shell. The other side of the end of the shell is connected to one side of the end of the connector by a thread. The connector is trumpet-shaped, and the other side of the end of the connector is fixedly connected to a metal part, and the inside of the metal part is connected to a refill by a through connection; the refill includes a pen tip, a limit The positioning block and ink absorbing block, the pen tip, the limiting block and the ink absorbing block are a unified whole, and are all made of carbon fiber.
