The Good Blue R615 Fountain Pen - Flame Grilled Polycarbonate

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 moulded plastic feed. And a polymer version should you prefer wetter ink flow.

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

The barrel and cap are precision machined from engineering grade polycarbonate rods, and then 'flame grilled' for a unique frosted effect.

Our grip section is machined from CZ121 brass and is untreated. It is precision textured with a surface roughness for ergonomic grip. 

Nib Choices

• Happy Medium - A wet, monoline medium, no flex. Perfect for that everyday writer or artist who likes a consistent line. Ships standard with machined plastic feed
• 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 Polymer Feed - Our Fine Flex nib with a specially designed polymer feed for wetter writing and juicy swells
• Titanium Flex - A soft, monster of a flex nib. Our wettest option puts down a ton of ink
• Zoom Nib - A non flex nib. Varying the angle of the pen to paper give you a fine to double broad line. Writes extra fine reversed.
