Pilot CON-40 Fountain Pen Converters Reviews

This converter lifts my Pilot MR Metropolitan to a new level. Definitely worth it.

Used in Metropolitan with Italic-Medium, Fine, & Medium nibs.

Pros: Best ink flow of all the Pilot Converts I've used so far. The filling action is smooth and the ink flow has been consistent with different types of inks.

Cons: You can hear the ball-bearings rattling if you jostle the pen around. While it has no functional impact on the performance of the pen, it makes it feel cheap and has lead to me being hesitant lending my pens to people.

If you need a converter, my opinion has this one well above the CON-50.

Beats the Con-20, higher in quality but tiny ink capacity.

Just a converter

The Pilot CON-40 does exactly what it's supposed to do... I used this to replace the squeeze converter that came with my Pilot Metropolitan, and I'm quite happy with that decision. The converter contains three steel balls to keep the ink mixing, and I've experienced only flawless functioning of this converter.

Lower capacity, but reliable and these work much better in the Pilot Metro pens (compared to the bladder fill converters that come with the pens). Only takes a second to refill so not a big deal for me - even for long writing sessions - they still last for many pages of writing and even when used for work purposes in the office, I may have to refill maybe twice a week

I cannot get this new model more than 2/3 full, which is frustrating. The prior design (with the black twister) seemed much better!

The Pilot CON-40 converter works just fine for me. I bought one of theseconverters with the four tiny balls that help ink from staying at the top of the converter for my Pilot Metro Retro Pop (fabulous fountain pens, by the way!) because I couldn't tell how much ink was left in the press style converter that came with the Metro. The press converter is a fine utilitarian converter and I'm certainly keeping it as a contingency, but I'm glad that I got the CON-40 replacement. It doesn't fill to the top, but few pens do and anyway an air pocket is a good thing for flow. The tiny balls are nifty for getting the ink from sticking at the top of the converter. They work. The clicking sound is so soft in my converter that I don't notice a click when I use the pen. Flushing ink residue from the converter has not been a problem for me. And I simply shake out any water that remains after I've expelled cleaning water from the CON-40. I will order more of these for a couple other Metros that I have - love the colors of the Retro Pops.

The CON-50 is much better. This CON-40 seems to hold less ink, causes burps often, and the twist knob is more difficult to use.

Not a great fan about the CON-40. Doesn't draw sufficiently enough ink in the converter. So I end up priming the pen then removing the converter to fill it by sharing.
