Sailor Special Edition Progear Slim Style of Lab Kosai-Hitsu Fountain Pen

Introducing STYLE OF LAB’s first original fountain pen: KOSAI-HITSU.

A true expression of the brand’s philosophy, Passion, Challenge, and Sophistication. KOSAI-HITSU brings together artistry and craftsmanship in a beautifully considered writing instrument. The design features graceful floral motifs inspired by delicate fragrances, rendered through Kaga printed maki-e, a traditional Japanese decorative technique known for its refined elegance.

At its heart lies a 14-karat gold nib crafted at Sailor’s Hiroshima factory, the same nib design recognized by Pen World magazine as the “Best Writing Fountain Pen in the World” for seven consecutive years since 2018.

Thoughtfully designed with a slender profile, KOSAI-HITSU sits comfortably in the hand, even for those who prefer a smaller grip while remaining compact enough to carry easily in a pen case or pouch.

With KOSAI-HITSU, STYLE OF LAB invites writers and collectors alike to embrace new possibilities through the art of writing.
