Description
The Sailor Iriomote Cat F3 celebrates one of Japan’s rarest native animals, the critically endangered Iriomote cat, a wild feline found exclusively on subtropical Iriomote Island in Okinawa. With fewer than 100 individuals remaining in the wild, the species is the focus of ongoing conservation efforts, making this distinctive fountain pen a tribute to both the animal and its fragile natural habitat.
The pen is crafted from a rich, chocolate-brown resin, with subtle dark spotting on the cap inspired by the Iriomote cat’s natural camouflage. The barrel features illustrations on opposite sides, offering two charming views of the animal.
One depicts an Iriomote cat facing forward, its wide, inquisitive eyes framed by characteristic striped markings. Turn the pen around, and a second illustration reveals a mother cat viewed from behind, with a small kitten peeking out from behind her back. The artwork combines warm tawny and tan tones with bold, leopard-like spots, bringing a playful quality to the pen’s otherwise understated appearance.
Gold-plated trim provides an elegant complement to the earthy resin, while the gold-plated Sailor F3 stainless steel nib, hand-finished by Sailor artisans, reflects the company’s attention to writing performance and craftsmanship. The pen is available with all five of Sailor’s hand-finished stainless steel nib sizes, allowing writers to choose the line width best suited to their preferences.
The Iriomote Cat F3 also supports an important conservation initiative. A portion of the proceeds from every pen sold will be donated directly to the World Natural Heritage Okinawa Conservation Consortium, helping fund species conservation and environmental protection in Okinawa.
Each pen arrives with an informational card introducing the conservation partnership, a matching collectible Iriomote cat sticker, an ink cartridge, and a converter. With its distinctive animal illustrations, practical writing features, and contribution to wildlife conservation, the Sailor Iriomote Cat F3 offers a thoughtful combination of Japanese craftsmanship, distinctive design, and environmental purpose.
Sailor is renowned for the quality of their nibs, and has sought to craft these steel tipping points with a precision and focus on the writing experience equivalent to that in the solid gold nibs for which the company has long been known.
Finer nibs from Extra Fine through Medium are highly suitable for everyday note-taking, while the Broad nib provides the smoothest writing experience and provides the greatest line-width on the page.
We do not ordinarily provide our free nib tuning and optional nib customization services on steel nib pens. For these services, please see our large selection of Sailor pens with 14k, 18k, and 21k nibs.
