As well as having such a great name for a brand – Nahvalur, the Icelandic translation of their former name, Narwhal – this New Jersey company offers a range of really striking pens.

This Nautilus is the first to officially adopt the construction and styling introduced during the launch of the limited edition 365 Plongeur. It’s slightly slimmer than the original design, with the cap sitting flush with the barrel, andit’s made of titanium with an ebonite feed.

It’s completely plated in black and is fitted with a stainless steel nib in a range of sizes.

The porthole-inspired ink-view windows are still there (thankfully) and it’s easily refilled with bottled fountain pen ink.
