Pilot Con-40 Converter for Fountain Pens

This converter is better than the one that came with my pilot metropolitan but it doesn’t hold much ink compared to standard converter that I use in many pens in my collection and it doesn’t hold a candle to the piston fill option that seems to gain in popularity. The small amount of ink it contains is one of the reasons why I avoid buying Pilot fountain pens.

Worked as needed, main gripe with this converter is that it runs out of ink quickly but overall easy to use

I was very annoyed with my Pilot Custom 742 with FA nib, which skipped every other stroke, thus breaking up my flow of writing.
I tried using different inks, including Waterman Intense Black, on different types of paper, to no avail.
I kept pondering on the issue, since I had a Falcon in SM, which gave out a lot of ink too, but never skip with the same inks nor paper.
When it was time to refill both pens, it dawned on me that the converter might be the problem. So I swapped out the Con-70 from the Custom 742 and put on the Con-40 instead. Sure enough, the ink flow greatly improved. So now I have to keep my bottle of ink handy during calligraphy sessions, since I need to refill after filling one and half page of A4 paper.

I am new to fountain pens but I highly recommend the piston-style converter over the bladder-style ink reservoir that comes with the Pilot Metropolitan fountain pen. Save yourself a step and just order the converter when you buy a Pilot fountain pen that has the bladder-style reservoir.
