It keeps everything the Demo does well: full visibility of ink, mechanism, and fill level, in a body that's unmistakably playful rather than purely clinical.\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 Demo's form is straightforward and well-proportioned: a straight-sided barrel and cap with flat finials, giving the pen a clean, architectural silhouette that sits comfortably in the hand for long writing sessions. Capped, the pen measures approximately 147 mm; uncapped, approximately 137 mm. Maximum diameter is approximately 16.5 mm, with a grip diameter of approximately 11.7 mm. Weight is approximately 27 g — light enough for extended writing without fatigue. A polished chrome clip completes the pen. Note that the Demo does not post — the cap does not attach to the end of the barrel — so the length you write with is the uncapped length.\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\"\u003eThe Demo 2020 Color uses a full Japanese-style eyedropper filling system, with the entire barrel functioning as an ink reservoir — capacity runs approximately 3.4–3.5 ml, several times what a standard converter holds. An integrated shut-off valve, controlled by a twist knob at the base of the barrel, seals ink above the feed when closed, preventing the thermal expansion that can push ink through the nib when a warm pen is uncapped or carried. Open, it allows steady, controlled flow from barrel to nib.\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, draw ink into the included glass pipette, deposit it into the barrel, and reassemble. Apply a thin layer of silicone grease to the barrel threads before closing to ensure a leak-free seal. The pen uses bottled ink only — no cartridges or converters are compatible with this filling system.\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 Demo 2020 Color is fitted with a #6 JoWo stainless steel nib, replaceable and 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 controlled, precise line for small handwriting or detailed annotation\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 option for most writing styles\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eMedium (M)\u003c\/strong\u003e — a broader, wetter line that brings out shading and sheen in expressive 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 — a broad italic-style nib 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.
