Introduced in the 2020 Philadelphia Pen Show, the Nahvalur Schuylkill series is named after the river that runs through the city of brotherly love. Building on the Nahvalur Original series, the Schuylkill series features exclusive resin materials made for Nahvalur, a piston fill mechanism, and a distinctive ink window. Nahvalur produces one limited edition Schuylkill every year. The year 2022 features a new color: Dragonet Sapphire. Inspired by the color of tropical sea creatures, Nahvalur mixed a new resin using red and blue as primary colors and paired it with rose gold trim.

This edition is a limited production of 2000 pens.
