The Opus 88 Jazz \"Cat Walk\" captures a crisp autumn afternoon in translucent resin — soft white ribbons of pattern drift across the barrel alongside delicate orange maple leaves, framed by a faint cat-paw motif that gives the edition its name. Deep ruby red finials cap each end, set off by polished platinum-finished trim in a cool silver tone. It's a quieter kind of limited edition — playful in concept, elegant in execution.\u003c\/p\u003e\n\u003ch4 dir=\"ltr\" class=\"mt-2 -mb-1 text-base font-bold\"\u003eDesign \u0026amp; Construction\u003c\/h4\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe Jazz silhouette is the same comfortable cigar shape the line is known for: rounded ends, no sharp tapers, and proportions built for long writing sessions. Capped, the Cat Walk measures approximately 151.2 mm; the body alone is approximately 133.2 mm, with the cap adding approximately 69.6 mm. Grip diameter is approximately 11.2 mm, and the pen weighs approximately 28 g — substantial in hand without tipping into heavy. The translucent resin keeps the ink level visible at a glance, so you always know how much writing you have left.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe pen ships in an Opus 88 gift box with a glass eyedropper pipette included for filling.\u003c\/p\u003e\n\u003ch4 dir=\"ltr\" class=\"mt-2 -mb-1 text-base font-bold\"\u003eEyedropper Filling System \u0026amp; Shut-Off Valve\u003c\/h4\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eLike other Jazz pens, the Cat Walk uses a Japanese-style eyedropper system with an integrated shut-off valve, controlled by twisting the blind cap at the end of the barrel. Closed, the valve seals the reservoir against the ink expansion that heat and altitude can cause — a real advantage for a pen that travels, including by air. Open, ink flows freely to the feed. Maximum ink capacity is approximately 2.97 ml, several times what a standard converter holds.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eTo fill: unscrew the grip section from the barrel, use the included glass pipette to draw ink, deposit it into the barrel, and reassemble. Before writing, unscrew the blind cap to release the internal shut-off mechanism and allow ink flow to the nib; tighten it again before travel.\u003c\/p\u003e\n\u003ch4 dir=\"ltr\" class=\"mt-2 -mb-1 text-base font-bold\"\u003eNib Options\u003c\/h4\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe Cat Walk is fitted with a #6 JoWo stainless steel nib, available in:\u003c\/p\u003e\n\u003cul dir=\"ltr\" class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3 print:block print:space-y-1\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eExtra Fine (EF)\u003c\/strong\u003e — a precise, controlled line for small handwriting\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eFine (F)\u003c\/strong\u003e — the most versatile everyday width\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eMedium (M)\u003c\/strong\u003e — broader and wetter, good for shading inks\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eBroad (B)\u003c\/strong\u003e — a bold, generous line\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003e1.5 mm Stub\u003c\/strong\u003e — an italic-style grind adding crisp line variation to every stroke\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eOpus 88 nibs tend to write slightly broader than equivalent Japanese sizes — if you usually reach for a Pilot or Sailor fine, consider sizing down one step.\u003c\/p\u003e\n\u003ch4 dir=\"ltr\" class=\"mt-2 -mb-1 text-base font-bold\"\u003eManufacturer Warranty\u003c\/h4\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eOpus 88 fountain pens are backed by the manufacturer's warranty against defects.
