Opus 88 

Taiwanese manufacturer Opus 88 has slowly evolved from something of a curiosity (nearly all of their pens utilize a high-capacity Japanese-style eyedropper system, something rarely seen in the U.S. and Europe) to a mainstay of the modern fountain pen scene. Featuring JoWo No. 6 nibs that are easily interchangeable, Opus 88 fountain pens are versatile workhorses that come in a wide range of styles, some quite quirky!
