Can Parker pen use other ink?

You can use other inks. But it's best to use gram ink. Gram ink is non-carbon ink, which will not block the nib, has the function of cleaning the ink outlet system, and can appropriately extend the service life of the pen.

Parker pen adopts a slender traditional tongue design, and an elbow extends from the end of the tongue, and the end of the elbow bends towards the wall of the ink reservoir and clings to the wall.

Parker has an exclusive patent on this design. Theoretically, this will make the ink flow back to the ink reservoir along the elbow when the pen is not used. /kloc-The competition in the pen market in the 1920s was fierce, and the "lucky curve" was Parker's advantage.

Extended data Parker pen vacuum series adopts a new ink conveying system. There is a diaphragm near the nib, which generates suction when pressed, and can directly suck ink into the pen holder. The pen holder itself is made of colored celluloid, and the remaining ink in the ink reservoir can be seen through the transparent stripes on the pen holder.

The redesigned thin-edged arrow-shaped pen holder is very distinctive (Parker still uses this design today), and there is a "blue diamond" enamel mark on it that promises a permanent warranty.
