Opus 88 has been crafting fine writing instruments in Taipei, Taiwan, since 1988 — initially as a precision OEM manufacturer for some of the most respected names in the pen world, and since 2005, under its own banner, quietly redefining what an eyedropper fountain pen can be.\u003c\/p\u003e\n\u003ch3 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eThe Taipei Standard\u003c\/h3\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe company was founded at the intersection of engineering precision and a deep love of art. The name \u003cem\u003eOpus\u003c\/em\u003e reflects this ambition — a declaration that the brand works fluently across materials: brass, wood, shell, sterling silver, acrylic, and ebonite. The number 88 marks the year it all began.\u003c\/p\u003e\n\u003ch3 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eThe Eyedropper Difference\u003c\/h3\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eOpus 88 pens are particularly admired for their eyedropper filling systems and transparent demonstrator designs. Unlike cartridge or converter pens, genuine eyedropper construction demands exacting tolerances — a system once reserved for the most high-end Japanese Maki-e pens. Opus 88's signature contribution is a screw-down shut-off valve that seals ink away from the nib when the pen is capped, enabling safe everyday carry with a barrel full of ink. The result is one of the largest ink capacities available in any modern fountain pen, without the leakage risk that typically accompanies eyedropper designs.\u003c\/p\u003e\n\u003ch3 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eThe Collection at Shosai\u003c\/h3\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe Opus 88 lineup spans a broad family of models — from the colourful resin-and-ebonite Koloro, to the sleek Jazz, the large-format Omar, the transparent Demonstrator, the playful Fantasia and Mini, and the refined Opera and Harmony. Each series carries a distinct personality while sharing the same foundational commitment: pens engineered to last, filled with your ink of choice, and expressive enough to stand apart in any collection.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eAt Shosai, we carry a curated selection of Opus 88 fountain pens, available in our Gatineau boutique and online, serving the Ottawa–Gatineau National Capital Region and beyond. Whether you are picking up your first fountain pen or adding a serious eyedropper to an established collection, Opus 88 belongs in the conversation.\u003c\/p\u003e","products":[{"product_id":"opus-88-demo","title":"Opus 88 Demo Fountain Pen","description":"\u003ch2 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eOpus 88 Demo Fountain Pen\u003c\/h2\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe Opus 88 Demo is the model that best explains why this Taipei brand has earned a devoted following among serious fountain pen users. Built from alternating clear and frosted resin in a flat-top cylindrical profile, it does something few pens manage: it makes the mechanics of writing visible. Every millilitre of ink in the barrel, every movement of the valve rod, every layer of sheen or shimmer in your chosen ink — all of it is on display, all the time. This is not decoration. It is a pen designed for people who want to understand what their writing instrument is doing.\u003c\/p\u003e\n\u003ch3 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eDesign \u0026amp; Construction\u003c\/h3\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe Demo's form is deliberate and uncluttered. The straight-sided barrel and cap, flat finials, and alternating panels of polished clear and matte frosted resin give the pen a clean architectural quality that looks equally at home on a writing desk or in a shirt pocket. There are no tapers, no ornamental flourishes — just a well-proportioned cylinder that sits comfortably in the hand for extended writing sessions. Trim and hardware details vary by colour — see individual variants for specifications.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eAt 147.6 mm capped and 136.5 mm uncapped, the Demo is a large pen by any measure. The grip diameter of 11 mm and overall weight of approximately 27 g make it substantial without being fatiguing. Note that the Demo cannot be posted — 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 leading-[1.7]\"\u003eThe pen is supplied in an Opus 88 gift box and includes a glass eyedropper pipette for filling.\u003c\/p\u003e\n\u003ch3 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eEyedropper Filling System \u0026amp; Shut-Off Valve\u003c\/h3\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe Demo uses a full Japanese-style eyedropper filling system, with the entire barrel functioning as an ink reservoir.

When closed, the valve seals ink above the feed, preventing the thermal expansion that can push ink through the nib when a warm pen is uncapped or carried. When open, it allows a steady, controlled flow from barrel to nib. The central valve rod can also be used to manually prime the feed — a detail that reflects the depth of engineering behind what appears, at first glance, to be a simple clear pen.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eTo fill: unscrew the grip section from the barrel, draw ink into the included glass pipette, deposit it into the barrel, and reassemble.

A classic cigar-shaped eyedropper pen built for serious, sustained writing, the Jazz has been one of Opus 88's most enduring models since its introduction — earning particular devotion among ink enthusiasts who want to see every drop of their favourite colour at work.

With 3–4 ml of ink visible through the barrel at any time, shading inks reveal their full tonal depth; sheening inks catch ambient light from every angle; shimmering inks with fine metallic particles turn the barrel into a constantly shifting display. The Omar is, among other things, one of the finest ink showcase pens available at any price point.\u003c\/p\u003e\n\n\u003cp\u003eOne practical note for clear acrylic variants: strongly pigmented inks — certain deep reds, purples, and blue-blacks — may lightly stain the barrel over time. Regular cleaning and thorough flushing between ink changes minimises this effect significantly.\u003c\/p\u003e\n\n\u003ch3\u003eLifetime Replacement Guarantee\u003c\/h3\u003e\n\n\u003cp\u003eEvery Opus 88 fountain pen sold at Shosai is backed by a \u003cstrong\u003elifetime replacement guarantee\u003c\/strong\u003e.
