Nagasawa Proske – Black Gold Fountain Pen

The Nagasawa Proske – Black Gold Fountain Pen is a sophisticated balance of Japanese tradition, modern transparency, and writing precision. With a semi-transparent black resin body that reveals the internal ink system and gold-plated accents that shine with subtle elegance, this pen embodies the refined aesthetic of the Nagasawa and Sailor collaboration. Based on the iconic Sailor 1911 Profit model, it was created for writers who appreciate beauty in functionality.

Concept and Design

The name “Proske” comes from blending “Profit” and “Skeleton,” highlighting its transparent demonstrator character. The smoked black barrel gives visibility into the inner workings while preserving a strong and serious silhouette. The bright gold accents offer a luxurious contrast, enhancing its presence without excess. It’s a pen designed for those who value detail and elegance in equal measure.

Functionality and Filling System

Fitted with a 14K gold nib, the Proske – Black Gold delivers a smooth, stable, and highly responsive writing experience. It supports both Sailor cartridges and converters, offering flexibility for daily or professional use. It comes with a converter and one cartridge, ready to be used straight out of the box.

Package Contents

At Inktraveler, we include a beautiful glass inkwell as a special gift, allowing you to enjoy bottled ink from the very beginning. The pen is presented in a carefully designed Nagasawa-branded box, making it perfect for gifting or personal collection.
