Nahvalur Nautilus Fountain Pen in Chelonia Green

Introducing the Latest Nautilus with Sleeker, more contemporary silhouette. The three refreshed Nautilus models: Stylophora Berry, Chelonia Green, and Maylandia Blue. Each pen has been reimagined in the striking Nautilus shape first seen in ebonite with our Cephalopod collection, offering a sleeker, more contemporary silhouette while retaining the craftsmanship and materials.

While the shape has evolved, the foundation has as well — each pen is still precision-crafted from premium ebonite, delivering the warm tactile feel and subtle texture prized by writing enthusiasts. For this redesign, all three models now feature elegant rose gold trim, adding a refined, cohesive accent across the collection. Each pen has also been upgraded with an Ebonite feed, making sure the writing experience is as refined as the design.

The Nautilus is outfitted with a stainless steel, number 6 size nib made in-house by Nahvalur in a range of nib sizes to suit your handwriting style. In this edition, Nahvalur improved the ink flow with an ebonite feed. The Nautilus fills using a built-in piston-filling mechanism that loads fountain pen ink directly into the barrel.

Writers enjoy Narwhal's nibs for their smoothness and consistency. The nib is interchangeable and can be removed by unscrewing the nib housing from the section or pulling the nib and feed straight out.
