The perfect ink for a $200 Pelikan pen; it cleans the nib during use.

Works great as a replacement, just be sure to clean your nib out before you change the ink or you might end up with a clogged pen.

Great option if already purchasing Pilot Metropolitan Collection Fountain Pen, Black Barrel, Classic Design, Medium Nib, Black Ink (91107).

Works well in my Metropolitan with a fine nib.

I may be able to start to see a bigger difference if I had a pen with a more flexible nib or was more of a fountain pen

My only tiny carp is that the medium nib writes more like a fine nib, but I have read that Japan makes their nibs on the narrow side

However, the Medium nib and this ink work perfectly together

So far only used one cartridge and still going strong after few months, the color is a nice true red that doesn't bleed or feather too much or at all with a medium to fine nib, but does dry quick which is a plus for me being left handed!

With a fine nib, it doesn't smear much, but it will soak through cheap paper

Ink is of decent quality but a bit on the thick side and there is some skipping problems with "F"(Fine) nibs

Currently using this ink for 2 of my Pilot Metropolitan fountain pens, one with a Fine nib and the other with a Medium nib

my Pilot Fine nib and my Pilot italic nib (from a Pilot Plumix).

As my new pen had a much finer nib and forty years have passed, I appreciated the instruction for installation because I didn't want to wreck the delicate parts

Once that was done, I then had to puncture the tip with a punch (carefully so as not to enlarge it too much) because my nib was unable to pierce the plastic seal

The ink passes the smudge test beautifully, and flow very smoothly from my Pilot Prera with fine nib.

It flows beautifully, I don't think I've ever had trouble with it clogging up the nib, and it puts a nice bold line on the page

Dries quickly enough on a fine nib pen to allow left handed writers to enjoy the experience of writing with a fountain pen

I got the fine nib Metropolitan to use at work

My fine nib looks as if it were a medium.

Before the nib was so scratchy from the other ink.

This ink writes just a tad too dry with the Fine nib, which makes the paper feel a little scratchy

Either the top of the cartridge was too thick, or the nib wasn't sharp enough to penetrate it.

Photos are wothbit heing used in my pilot metropolitan fine nib on moleskine paper

I use these cartridges with my Pilot metropolitan (fine nib) to write case notes with and went through a cartridge in 11 days

and I' Very Satisfied with the product

nice i like it
