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). The overall form is described by a single elliptical curve and a flat plane. Beauty through mathematics. The flat sections line up to make a roll stop across three components: A Swiss watchmakers’ technique. 

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

The center of mass of the pen sits in the stainless steel grip section to allow a neutral balance and better control of writing pressure for flex. 


Take your pick from our selection of nibs and feeds

  • Fine Flex Plastic Feed - Black PVD coated version of our stainless steel Fine Flex 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 Polymer Feed - Black PVD coated version of our stainless steel Fine Flex nib with a specially designed polymer feed for wetter writing and juicy swells

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 accommodates 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.


The stainless steel grip section and nib are coated black using a state-of-the-art Physical Vapour Deposition process. Similar to what's used in high-end watches. PVD produces an ultra thin but very durable coating, less than 5 microns thick! This ensures the nib performance is unaltered. And the micro texture on the grip section is retained. The barrel and cap are matte finished black anodised aluminium.
