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.
