An improved pen, characterized essentially by being composed of a housing containing the ink-carrying tube whose cap is chamfered, and which, in a large internal upper cavity, contains a cylindrical head sleeve provided with a frustoconical cavity, and a ball of diameter somewhat larger than the space between the ink carrying tube and the side walls of the upper cavity, and somewhat smaller than the diameter of an existing hole in the cap of the housing, in which it is susceptible to be introduced, as well as the tube carrying the ink, when the pen is turned upside down.
