OPUS 88 Harmony fountain pen

The Harmony series is closer in size to Kooloo's smaller models, making it more suitable for most users. Manufactured in Taiwan by OPUS 88, a brand with over 45 years of experience in writing instrument production, this series utilizes OPUS 88's signature Japanese drip-filling system, blending the romance of classic drip-filling with the reliability of modern sealing technology.

Harmony Flower (Colorful Falling Flowers)

Red, blue, yellow, and green speckles, like petals scattered across the transparent acrylic barrel, create a kaleidoscope-like visual effect. The Demonstrator's transparent design makes the ink an integral part of the writing experience. Paired with rose gold metal hardware, this is a limited-edition color for the OPUS 88, released in 2026—bright, optimistic, and playful.

Writing experience:

• JOWO No.6 steel nib with rose gold plating, available in EF / F / M / B / 1.5 Stub / Flex EF / Flex F nibs (depending on the model).
• Air valve construction: A hard rubber piston, combined with a rubber sealing ring, can isolate the ink channel when tightened, reducing the risk of ink leakage during air transport and inkjet printing.
• Drop-in ink filling: When used with a glass dropper, it can hold a large amount of ink, allowing for continuous writing.
