Opus 88 Koloro Fountain Pens / Ebonite

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. 

The colorful "Koloro" pens use a bold color-blocking technique combining acrylic and hard rubber. This combination of different materials creates a stunning appearance and offers a more comfortable grip and a light weight for 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.
