Q: What is the difference between the Pilot Fountain Pen Ink Catridges and the Pilot Namiki Fountain Pen Ink Cartridges?
As far as we can tell, there is no difference between the Pilot and Pilot Namiki fountain pen ink cartridges besides the packaging and number of cartridges per package. The Pilot cartridges are packaged for the Japanese market, while the Pilot Namiki cartridges are packaged for the North American market.
Looks just like the green ink from Precise roller-ball pens! I love writing in
green and the Namiki ink flows very well in my Pilot Metropolitan pens. Smooth,
legible, and more expressive than blue or black.
