Introduced in the fall of 2021, the Nahvalur Nautilus combines vintage materials with modern designs. When fountain pens were first invented, all pens were made of a hardened rubber called ebonite. Today, hardly any pen companies are still using this beautiful material. The Nautilus series is bringing back this retro material while combining modern design elements. Three portholes are carefully crafted onto the body of the pen to allow users to view the ink reserve.
