The Leviathan Prototype nib. My obsession with reverse-stacked nibs, expressed to the highest level of absurdity. Manifesting the monstrous form of this nib’s namesake; this acts as the final progression of the Serpent Sequel nib. Five layers, welded together, with two nibs under-stacked to create a fluid transition to the rest of its form. I wanted this nib’s lines to flow into the rest of the pen body that holds it.

Its function should be familiar, yet as startling as I can manage. A western Fine on the regular side; reversible to a 5MM paintbrush - with line size according to the users’ writing angle.

This Leviathan, being a very special prototype, will be paired with an equally stunning custom-built fountain pen body. A bespoke experience by Regalia Writing Labs, where I will work one-on-one with the owner to create a complete vision for this nib from tip to tail.

 Compatible with all pens that accept a JoWo #6 screw-in housing unit.

This includes fountain pens from companies like: Edison Pens, Franklin-Christoph, Opus 88, Newton Pens, Desiderata Pens, and many, many more.

[NOT compatible with Bock nib systems, Jinhao, Nahvahlur, TWSBI, Monteverde, or Conklin]

Please Note

The nib comes as a unit, including the feed and housing. It is installed by screwing the unit into the pen body. It is highly recommended that you do not remove the nib from the feed. The "breather" at the end of the ebonite feed is extremely fragile and is easy to accidentally break when removing the feed from the housing. Replacement feeds cannot be provided. 

Please be mindful of your writing pressure.

They are not meant to be flexed or to be used heavy-handedly, and have the potential to irreparably "spring" if pushed too far, which will destroy the nib. I cannot offer refunds, replacements or repairs in the event of user-error.
