 "Game-changing!" Sumi - The Flexible Fountain Pen

**YOUR SUMI IS DIP DYED BY HAND SO PLEASE ALLOW 2 WEEKS FOR US TO MAKE AND DISPATCH YOUR PEN**

Why isn’t there a fountain pen that writes like a calligraphy pen with no need to dip it in ink?  This is the question I asked myself three years ago. It seemed no one had a good answer so I set about answering it myself.  And after a pile of prototypes, failed experiments and a lot of head scratching, I’m very proud to introduce you to Sumi - The Flexible Fountain Pen!

"Tom has done it again! I mean...just look at it! This is his new fountain pen that has a flexible fine nib which means you can have your thick and thin lines without having to dip your pen in ink every so often!"

Hazel's Lettering (professional calligrapher)


The Sumi's secret ingredient is the custom, super-flexible nib which allows you to write as thin as 0.4mm, and up to 2.0mm when fully flexed. It’s also tipped with a German iridium tip for a smooth writing experience (no more scratching or ink splatters) and, unlike standard calligraphy nibs, it will last a lifetime.

 


It's springy, fun to use and incredibly addictive!



The Sumi pen comes with an ink converter (a fancy re-fillable ink cartridge) which means you can use the pen with 100s of different coloured fountain pen inks. I highly recommend using Diamine Inks which have been specifically tested for use with the Sumi pen. They’re lovely and juicy and even have a metallic colour range which shimmers in the light! We do not recommend using ink cartridges with the Sumi pen as the ink flow will not keep up with your writing and is likely to result in 'rail roading'. 


READ ON IF YOU LIKE THE DETAILS...

Just as the function of the pen honours calligraphic heritage, the form is also inspired by a traditional quill and ink set. I’ve paired the design back and have also infused the aesthetics with a minimalist Japanese look (hence the name Sumi which means ‘ink’).  The making of the pen is a different story, and is firmly rooted in the 21st century. By using state of the art CNC watchmaker’s lathes I can create a supremely refined and well balanced pen.

A big question (which, as a designer I often grapple with) is this: ‘We are all individuals so why are the products we use on a daily basis so often utilitarian and say so little about us and our own individuality?” It’s the reason I wanted to create a pen which is as unique as its owner. So I spent a lot of time developing a new dyeing process taken from fine jewellery production techniques.  Every pen is individually dip-dyed by hand using this technique, making each one subtly unique.

Sumi - Flexible Fountain Pen, designed to celebrate creativity, craft and individuality. 





Good to know & FAQs:
  • Full FAQs can be found here.

  • The brass stand has been designed to be equally happy standing on your desk, or in your bag on the go.

  • The Sumi pen works beautifully with all Diamine Inks (including shimmer!) You can find them here).  Be sure not to use calligraphy specific ink as this can clog the pen.

  • Like a good pair of leather shoes the Sumi Pen will soften and become even more flexible with use. It will adapt to your style of writing and become unique to you. As such, it may take a little time for your pen to ‘settle in’. If you have any questions at all about the functionality of your pen, please get in touch as we are always very happy to help.

  • We recommend you flush your Sumi pen thoroughly before use. This will remove any oils from the nib which are present during manufacture, and will impede ink flow. Any of the following are good options: our Nib Cleaning Solution, distilled water or water with a touch of dish soap.
  • If you are having any problems with your nib 'rail-roading', this is usually down to ink flow issues and residual oil on your nib (see above). Make sure you are writing slowly so that the ink has a chance to catch up with your writing. 
  • The Sumi pen is designed to compliment your calligraphy pen and not replace it entirely. If you're looking for the maximum softness and flex please take a look at my Flourish Pens.

  • Measures 165mm with brass stand, 150mm without and weighs 67g with brass stand, 25g without.

  • Each pen is beautifully presented in a gold foiled gift box.

  • Every pen is machined from solid metals on a lathe used for making fine watch and aerospace grade components, so you can be sure your pen will write perfectly for years and years to come.

  • Brass naturally develops a patina over time and with use. You can choose to embrace this unique change or our brass polish to bring it back to it's gleaming best.

  • Every Pen is dip dyed by hand so may have small speckles or colour variations; it's part of what makes your pen unique and is not considered a fault.

  • We offer a complimentary repair service, so should your Sumi pen need a little TLC please contact us .
