The pen is filled by unscrewing the nib group and inserting the ink directly into the body of the pen, as for the ordinary [[eyedropper filler]]. However, to avoid possible losses, which would be disastrous for the traditional clothing of the Japanese (the kimono), the pens equipped with this system are equipped with a piston mounted on a shaft operated through the bottom of the pen. When the bottom is screwed on, the piston, which serves exclusively as a blocking valve, comes into contact with the nib group, blocking the access of the ink to the same, so as to prevent any possible leakage.

Per poter scrivere occorre svitare il fondello e ritirare leggermente l'alberino ad esso agganciato, in modo da ritrarre il pistoncino dalla sua posizione di blocco e riabilitare il flusso dell'inchiostro verso il pennino. Richiudendo il fondello si bloccherà nuovamente l'afflusso di inchiostro, prevenendo così le perdite.

In order to write it is necessary to unscrew the bottom and slightly withdraw the shaft attached to it, so as to retract the piston from its blocked position and re-enable the flow of ink towards the nib. Closing the bottom will stop the ink flow again, thus preventing leaks.
