Abstract: A felt pen or a like writing instrument includes an elongate body having a cavity defining a first chamber housing a plug of hydrophilic material associated with a writing tip one end of which projects out of the body. The body also includes a second chamber separated from the first chamber and defining a reservoir for liquid ink for supplying the writing tip. The writing tip is spaced from the second chamber and can be supplied with ink directly from the-plug which draws ink from the reservoir through capillary supply means independent of the writing tip and interposed between the first and the second chambers.
