Extra Fine Semi-Flex Fountain Pen Nib
A beautiful extra fine fountain pen nib with flex! This nib strikes the perfect balance between our Pro Flex and classic fountain pen nibs, offering a smooth writing experience with minimal upkeep. With gentle pressure, it elegantly flexes from 0.5mm to 1.5mm, allowing for expressive line variation.
Made exclusively for our fountain pens, all nibs are tipped with hard-wearing iridium for effortlessly smooth writing. You can choose between uncoated stainless steel (a sleek silver finish) or 14k gold plating (a classic gold finish) – the difference is purely aesthetic, so both options offer the same exceptional performance. Plus, every nib is interchangeable, allowing you to effortlessly switch styles whenever inspiration strikes.
Introducing Our Limited-Edition Ebonite Feed
Looking for a little something extra for your writing setup? Enter the Ebonite Feed. Unlike our injection-moulded feeds, ebonite is a game-changer for ink flow. Its natural hydrophilic properties (think super ink-grabbing powers) mean it holds more ink, giving you a smoother, wetter writing experience that’s perfect for those who like their pens to glide across the page.
This limited-run feed is part of an experimental release – we’ve sourced just a small batch to see what you think. If you’re all about peak performance, this might just be your new favourite upgrade.

Customer Reviews
I have bought both versions of the extra fine semi flex. Both are superb giving brilliant variation in line quality, but the ebonite version allows the ink to flow more smoothly and consistently. It really is worth paying the extra for this - it is a really game changer.
I just purchased the Extra Fine Semi-Flex Fountain Pen Nib with the Ebonite feed and I love it! It writes really well...not temperamental at all. I do need to press a bit when wanting thicker lines, but I'm fine with that. I'll be using this for artwork....doodle shown gives a good idea of line variation. I'm happy! :)
What a brilliant nib! My old EF semi-flex was a bit temperamental, especially in environments with lower humidity, but this one has all the good qualities of my old nib (nice thin lines for my small handwriting) and none of the temperament. Brilliant, brilliant nib!
I was convinced this would be the problematic nib - esp. as there are only 2 reviews (surprising?) While I'm not the greatest fan of fine writers, this nib is a beauty. It works better than the cursive/italic. The writing flow is lovely, producing delightful, delicate lines, and sometimes the whiff of cursive, which I'm sure would be better if I were more expert.
Really recommend this.
Eager to try yet deciding on colors to cast to create a home yo use this in
