This is a Pre-Order item. See our Pre-Order Policy.


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 brass grip section to allow a neutral balance and better control of writing pressure for flex.

Our grip section is machined from CZ121 brass and is untreated. Over time it will age and develop a unique patina personalised to you. We think this is wonderful, but should you want to restore it to the original, all it needs is a gentle polish with any standard brass polish and a clean cloth.



Choose your Nib:

Fine Flex Plastic Feed - A ‘fine’ nib that flexes happily to 1.4mm with standard plastic machined feed that keeps the ink flowing. It’s tipped, so works great for everyday writing too.

Fine Flex Polymer Feed - Fine Flex nib with a specially designed polymer feed for wetter writing and juicy swells.

Titanium Flex - A soft, monster of a flex nib. This is the wettest option and puts down a ton of ink.

Untipped Calligraphy Flex - A soft, untipped flex nib that produces extra fine hairlines and juicy swells. Great for calligraphers, but too scratchy for everyday writing. Made from stainless steel so it won't rust or corrode.
