The writing implement using liquid ink is constituted by: a) a body whose rear portion constitutes a reservoir for the ink; b) a transfer rod whose rear end opens out into the reservoir and whose front end projects out from said body and forms a writing tip; and c) a buffer reservoir in contact with the transfer rod. The surface tension of the ink lies in the range 21 mN/m to 25 mN/m, and is intended for use on non-absorbent media made of metal or of plastic. The surface tension of the material constituting the buffer reservoir is less than that of the ink by a determined difference which is preferably equal to or less than 4 mN/m, thereby enabling the buffer reservoir to absorb and give back any excess ink coming from the transfer rod by capillarity in the event of variation in the pressure inside the reservoir. The buffer reservoir may be made of a material whose surface tension has been lowered by depositing an agent whose surface tension is less than that of the ink while lying within the determined difference, e.g. fluorine, polysiloxane, or a fluorine-containing resin.
