Beauty is in the eye of the pen holder

Choose between 7 glorious nibs. There are two categories, my bespoke fountain pen nibs (with their creativity-inducing engraving) and the Pro-Flex calligraphy nib. 
Please read my FAQs to help you make the best choice when choosing your nib.

Fountain Pen Nibs:

Made exclusively for our fountain pens, all of my nibs are tipped with incredibly hard-wearing iridium for super smooth writing, and are plated in a 14k gold for a classically stunning look. As a bonus all nibs can be interchanged so you can easily write in different styles whenever it suits you.

  • Extra Fine Semi-Flex - A beautiful extra fine fountain pen nib with flex! This is a great middle-ground between the Pro Flex and our classic fountain pen nib, with its smooth writing experience and minimal maintenance. By applying a little pressure the nib will flex from 0.5mm to 1.5mm.

  • Fine - A springy and smooth nib perfect for delicate thin strokes, with a smidge of flex if you're feeling creative.

  • Medium - The go-to nib for the author, journaller or note-taker. This is a firm and consistent nib for everyday writing.

  • Architect Fountain Pen Nib - This is the opposite of the Italic nib, with a broad cross stroke and a thin down stroke. It's my personal favourite - the effortless big juicy lines make it my go-to for sketching and everyday use. It's a BB (double broad), which means it has nice line vairation and strokes around 1.2mm at it's thickest. You can also use the nib upside down for a super fine stroke.

  • Cursive Italic Fountain Pen Nib -  is a specialized nib that is designed to produce line variations in handwriting. It is a type of italic nib that has a smooth, rounded tip that is slightly flattened on the sides. This flattening creates two distinct writing surfaces: a broader downstroke and a thinner horizontal stroke.

The term "cursive" refers to the flowing nature of the script that is produced by this type of nib. The BB designation stands for "double broad," indicating that the nib produces a broad line that is twice as wide as a standard broad nib.

With practice the cursive italic nib can produce stunning handwriting that is both distinctive and elegant.

  • Titanium - This beauty is the ultimate flex as it's a lot softer than stainless steel nibs. It's perfectly paired with our fountain pens to practice calligraphy when you just want to get cracking without having to prep all your nibs and ink or you're out and about.  Titanium is also bombproof so it will carry on writing for decades to come.  It's the best flex nib with the least maintenance.
Pro-Flex - Extra Inky
  • I've designed the prototype Pro-Flex with an innovative leaf spring which moves with the nib.  It's a 3D printed white feed (which by happy accident changes colour depending on the ink used in the pen).  It's early days but we've had rave reviews from customers and calligraphers alike and it seems to be performing as well as the original Pro-Flex for consistent ink flow when fully flexed. All feedback welcome to further improve the design! Please note this uses a specialist calligraphy nib which will need replacing (buy replacements here) read more about this special nib here:

Extra Fine Semi-Flex - Extra Inky

I've applied the same 3D printed white feed design (which by happy accident changes colour depending on the ink used in the pen) to the Semi-Flex nib for improved ink flow.  Because this is fitted with a flexible fountain pen nib, this option is for the casual calligrapher who likes the flexible fun this nib provides without the faff of changing a professional calligraphy nib when it corrodes.

Semi-flex perfection

I bought the semi-flex having previously bought the Pro-flex but having been too lazy for the necessary care that the Pro-flex demands. Don’t get me wrong, the Pro-flex is great, but not it you are too lazy to keep cleaning the ink out of the nib and to keep changing the nib. The semi-flex is wonderful - it still has quite a lot of flex when writing emphatically, and less when writing at speed - but this is a workhorse of a pen nib - to write journals, to scribble notes and shopping lists, but also one to write cards and letters. I love the semi-flex - it does everything I want with minimal maintenance.

Perfect EF nib with just enough flex to allow me to practice my calligraphy lettering in my journal and planner, eliminating the need for two pens. Writes beautifully smoothly and is easily interchangeable with my medium nib if I feel the need for a bolder font. Just perfect!

Really interesting nib.

Bought my first architect nib here, and it's a joy to write with. I had to change our the nib and feed housing to fit my Majohn C1, but it was simple enough. The pen writes like a dream, and the detailwork on the back/top of the nib looks great.

Nice shaped size 6 titanium nibs

These size 6 titanium nibs fit all #6 nib size range of pens. I’ve fitted one to a titanium Namisu fountain pen with the nib’s own feed and threaded sleeve and another to a Ranga pen for which I had to take the nib out to fit to the Ranga feed and sleeve. They work perfectly and are an excellent alternative to Bock titanium nibs.

Wonderful Custom Italic

Lovely fat and juicy CI. Very clean lines with no sharp edges, that some CIs can have. Really it's a blend of stub and CI, that's very easy to use and a great way to experience line variation to make your handwriting more interesting. Service was excellent with a quick delivery. 👍👍
