Filling the pens is done with the principle of the [[match-stick filler]] through two small holes on the body which, when the pens are in theirs rest position, provide access to the pressure bars that allow to wring the grommets placed internally of both pens, that contain the ink. In this case it is not necessary to obtain a match-stick, given that the head of the cap mounts inside a thin metal shaft suitable for the purpose. Therefore you simply need to unscrew it and use it as a handle to push through the holes in the side.
