Opus 88 Harmony Mocha Mousse Fountain Pen

Opus 88 Harmony Fountain Pen - 2025 Mocha Mousse

Made in Taiwan, these new Opus 88 fountain pens feature a huge ink capacity as well as a unique, Japanese style eye-dropper filling mechanism. The pen has an ink shut off value to prevent ink from leaking into the cap during travel or changes in air pressure. During longer writing sessions, leave the shut off valve open so ink can make its way down into the feed.
