on saleGoulet #6 Steel Flex Nib - Silver

Took a gamble on fitment, but it is a perfect match for a Bock #6 Nib swap on my Karas Kustom InkV2 fountain pen. As others have said, there is not a lot of flex, but you can still get reasonable line variance. I use an EF, so too much flex would likely make my writing even more illegible since I write so small. Flow does seem to get a little cantankerous when I don't write for a few days with high-shimmering inks. That is pretty expected, though, so I can't really fault the nib.
I give it five stars because it is a good value for the price, and has worked well for me. Sure, there might be better flex nibs out there, but they are likely not as cheap as this.

Great experience this nib. Slightly misaligned tines out of the box but after aligned great experience overall. It's the sweet spot of a soft bouncy nib that doesn't consume too much ink and you can use it daily for normal writing. Wouldn't call it flex. I knew what to expect and wasn't disappointed cause I watched the YTube video about it.

The question of flex in a pen nib is often one of degree. You get an antique Waterman 52 with an original nib, it is going to have a ton of flex, and much more so than the modern standard "nail-hard" nib. Then there are flex nibs like those sold on pens coming from India - very flexible by today's standards. The Goulet nib fits somewhere in between one of those modern India nibs and the standard modern nib. You get decent line variation and a more interesting laydown of ink on paper, but not super-flex. These are marvelous nibs and give great variation on the page/

I was expecting to get slightly flexy but the noodlers ahab konrad and creeper flex more than this thing however if you arent into flexing a whole bunch it is a great ef nib

Looks good haven’t tried it yet but looks good
