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.
The ink turns darker with increased use, so don't despair if the color looks too
light initially. Appears more like a dark blue than dark gray ( like the lamy
blue-black cartridge). The shade is darker with the fine point nibs. Easy on the
eyes against yellowish tinged paper.
I use the pilot fountain pen for taking notes and at first i found the ink to be
too light. But then upon extended use, the ink turns darker--i dunno if it's the
pen or the ink, but it is great! I like this better than the black.
Good tone after a sentence or two is written. This works very well in the Pilot
Metropolitan with Fine nib and the Pilot Penmanship pen with the Extra Fine nib.
I had used Lamy Blue-Black, but found its thicker viscosity tended to gum up
Soon I'll be getting a Pilot Original Cuson in XF and my guess is that it'll be
the one that won't block up the nib.
This ink, in my opinion, leans to be a darker blue over a blue/black, but there
color is growing on me. The cartridges last about a week and a half for me, and
I write several pages per day with the pen. The ink is just wet enough for me.
Overall, a good quality ink.
