The Opus 88 Demo 2021 Yellow Fountain Pen is a vibrant, high-capacity writing instrument that celebrates the Pantone 2021 Color of the Year, "Illuminating." Known for its oversized presence and "Japanese-style" eyedropper engineering, this pen is a favorite among enthusiasts who want to see their ink sloshing inside a crystal-clear, sun-drenched barrel.
✨ Signature Features: The Sunlit Demonstrator
-
2021 Yellow Edition: Crafted from high-grade transparent yellow resin, this pen captures the "warming yellow shade imbued with solar power." It is accented with chrome trim and a grey blind cap and finial, reflecting the Pantone 2021 "Ultimate Grey" pairing.
-
Massive Eyedropper Capacity: The entire barrel serves as an ink reservoir, holding approximately 3.5ml to 4ml of ink—dwarfing standard cartridges and converters.
-
Shut-Off Valve System: A signature Opus 88 feature, the ebonite center rod acts as a shut-off valve. When screwed down, it seals the feed from the barrel, preventing leaks and "burping" caused by air expansion during travel or temperature changes.
-
Premium Jowo #6 Steel Nib: Equipped with a dependable German-made stainless steel nib that offers a smooth, consistent flow.
-
Extensive Nib Selection: This limited edition offers a size for every hand, including the crisp Stub 1.5 for calligraphy and the sought-after Flex Fine and Flex Extra Fine for vintage-style line variation.
🖋️ Experience & Specifications
-
Construction: Precision-turned acrylic resin with metal copper and ebonite internal components.
-
Weight & Balance: At 27g, the pen feels substantial but balanced. Note that it is non-postable (the cap does not sit on the back), maintaining its clean, architectural lines while writing.
-
Filling Mechanism: Authentic eyedropper (includes a glass dropper in the box).
-
Cap Mechanism: Secure screw-on cap (requires approximately 3.5 turns) to ensure an airtight seal and prevent the nib from drying out.
Why Choose Opus 88 Demo Pen?
The Opus 88 Demo 2021 Yellow is for the writer who views ink as an art form. The transparent yellow body transforms based on the ink you choose—imagine a deep orange ink creating a glowing sunset effect or a teal ink for a striking contrast. It is a "personality pen" that offers the best ink-to-weight ratio on the market, backed by a leak-proof valve system that makes it a practical travel companion despite its massive capacity.
"The 2021 Yellow Demo is essentially 'joy in a pen.' The transparency is so crisp that you can see every detail of the shut-off valve and the nib assembly. If you love long writing sessions, the Flex Extra Fine nib is a dream—it gives you that expressive 'bounce' without the maintenance of a vintage gold nib. Pro tip: For the best visual effect, use a high-shading ink. The way a shading ink looks through that yellow-tinted resin is absolutely mesmerizing, like looking at liquid stained glass."
