Single mindedly designed to produce beautiful flex lines. Precision engineered to be your pen of choice. 

The R615 is designed to be as simple as possible (but no simpler). This 3D printed version is simple, light weight and black. Matt black!

The feed design is fine tuned to bring you two options. An efficient and reliable injection molded plastic feed. And an ebonite version should you prefer wetter ink flow.

Please note, this product is printed on demand and may take up to 4 days to dispatch.


Take your pick from our selection of nibs and feeds

  • Fine Flex Plastic Feed - A ‘fine’ nib that flexes happily to 1.4mm with our standard plastic machined feed that keeps the ink flowing. It’s tipped, so works great for everyday writing too
  • Fine Flex Ebonite Feed - Our Fine Flex nib with an ebonite feed and collar for wetter writing and juicy swells
  • Untipped Calligraphy Flex Ebonite Feed - Our soft, untiped calligraphy nib for extra fine hairlines. Not suitable for everyday writing.

It’s all standardised and interchangeable

We like to chop and change and hack and try. The R615 reflects this philosophy - you can make it your own. All our components are international standard and can easily be interchanged with many leading brands.

  • Jowo Standard #6 Nib Unit - The R615 will accommodate Jowo #6 Nib Units.
  • Standard #6 nib - most #6 nibs will fit The R615. But not all, due to different nib curvatures.
  • International standard cartridge converter - we’ve got you covered with Schmidt’s excellent K5 converter. But if you want to swap this out or use cartridges - international standard is the way to go.



All components of the pen are 3D printed using a PA12 polymer, and dyed black. Matt black.
