Opus 88 “Koloro” – Fountain Pen Review

Opus 88 is a Taiwanese company (such as TWSBI, for instance) that has been active since 1988 as an OEM/ODM supplier, but only recently has caught the attention of many fountain pen enthusiasts in the end consumer-world. The reason for that is a pretty interesting pen named “Koloro” – a very affordable semi-ebonite eyedropper pen – in combination with well-thought through opinion leader-marketing in order to trickle down the word into the community.

The latter included me as well – Opus 88 has kindly shipped me a Koloro, and I gladly fulfill my duty to serve the pen community with a review of this pen.

Before we hop into the review, let me point you to Fontoplumo or Papier und Stift, where you could conveniently get the Koloro in Europe (no affiliate – just a friendly pointer).

But now, check out the video-review below, which is as always preceded by some quick facts. Again, I hope the review is helpful and that you enjoy watching it!

    Looks like a JOWO nib. Bock nibs and feeds are more rounded (on the bottom).

      That’s what I thought as well. But I have also heard other information. Unconfirmed, that’s why I did not speculate.
