Opus 88 Koloro Fountain Pens / Acrylic

Opus 88 is a Taiwanese manufacturer specializing in high-quality, affordable, and traditional eyedropper pen designs. All Opus 88 pens feature a Japanese-style eyedropper system, which uses a stopper valve to prevent leaks when the pen is in transit and not actively being used. When you are ready to write, simply loosen the blind cap to open the valve and allow the ink to flow. Japanese-style eyedroppers have a large ink capacity, making them excellent choices for travel. 

This version of the "Koloro" fountain pen combines highly polished clear acrylic with darker sections and blind caps, allowing you to showcase your ink of choice. The Koloro is a relatively compact pen, notable for its light weight and comfort over longer writing sessions. 

Opus 88 pens are made in Taiwan. The Koloro features a No. 5 JoWo nib unit, and each pen ships with a glass eyedropper for filling the pen.
