The Opus 88 Koloro 2025 Fountain Pen is a favorite among writing enthusiasts, combining generous ink capacity with thoughtful, high-performance design. Built for long, uninterrupted writing sessions, this model showcases Opus 88’s signature eyedropper filling system in a sleek, modern form.

Crafted from high-quality acrylic, the Koloro 2025 is available in Black, Hot Pink, and Light Blue. Its transparent barrel allows you to easily monitor ink levels, adding both function and visual appeal. The pen features an advanced eyedropper system with an internal shut-off valve, controlled by a rear knob, giving you greater command over ink flow—an innovation typically reserved for higher-end fountain pens.

Fitted with a smooth-writing JOWO stainless steel nib, the Koloro delivers a reliable and enjoyable writing experience. Each pen includes a convenient bulb eyedropper for easy filling, with a generous ink capacity of approximately 2ml.

Soft, luminous, and quietly captivating, the Opus 88 2026 Cloud Dancer Harmony Fountain Pen brings an ethereal new look to one of Opus 88’s most anticipated annual releases. Created as the 2026 “color of the year” edition for the Harmony model, Cloud Dancer pairs dreamy pearl resin with warm rose gold accents for a writing instrument that feels both elegant and serene.

The standout feature of this release is its beautifully crafted resin. With a soft, semi-opaque finish and a gentle gray-blue undertone, the material shifts subtly in the light, creating an airy, refined appearance that perfectly reflects the Cloud Dancer name. Rose gold trim adds a layer of warmth and sophistication, offering a striking contrast to the cool, luminous body.

Thoughtful design details elevate this edition even further. The center ring is engraved with Opus 88, while the finial features “The Harmony” in elegant script. A delicate ballerina emblem in rose gold graces the back of the cap, and just beneath where the cap rests on the barrel, “2026 Cloud Dancer” is printed in matching rose gold—an understated mark of this special annual release.
