Nagasawa Original Professional Gear Aqua Planet Limited Edition Fountain Pen

The Nagasawa Original Professional Gear Aqua Planet Fountain Pen is a vivid boutique collaboration between Nagasawa Stationery Center of Kobe and Sailor — part of Nagasawa’s renowned series of Japan-exclusive Professional Gear releases inspired by Kobe Ink Story colors and oceanic themes. Produced in limited quantities and primarily distributed through Nagasawa’s Kobe storefronts, these collaborations are highly collectible among Sailor enthusiasts.

The Aqua Planet edition captures the luminous beauty of water and sky through a striking transparent aqua-blue resin body, accented with complementary tonal variations that evoke shifting ocean depths and light reflections. The colorway reflects Kobe’s coastal identity and aligns with Nagasawa’s tradition of translating regional inspiration into expressive pen finishes.

Built on the classic Professional Gear platform, the pen features Sailor’s signature flat-top silhouette with balanced proportions and refined detailing. Polished silver-tone trim enhances the cool aquatic palette, while the cap finial is adorned with Kobe-themed branding that distinguishes Nagasawa exclusives from standard Sailor production models.

The pen is fitted with Sailor’s dependable 21K gold nib, engraved with Nagasawa-specific markings and tuned to deliver the brand’s hallmark writing experience — smooth yet precise with controlled feedback and excellent consistency across nib sizes. The pen utilizes a cartridge/converter filling system, allowing flexibility between Sailor proprietary cartridges and bottled ink via converter.

Like many Nagasawa collaborations, the Aqua Planet was produced in limited numbers and released primarily within Japan, making it increasingly difficult to source internationally. Its vibrant demonstrator aesthetic, Kobe heritage, and Sailor craftsmanship combine to create a piece that appeals equally to daily writers and collectors of boutique Sailor exclusives.
