Opus 88 Koloro Fountain Pen Review

Opus 88 Koloro Fountain Pen Review

Appearance

The Opus 88 Koloro Fountain Pen has transparent sections that allow you to see the ink levels inside. The Koloro also has ebonite sections that compliment the resin and give the pen a nice clean look. The Koloro comes in four different colors and is available in three nib sizes. Pictured here is the popular Blue Tan color of the Koloro. All of the Koloro’s come with chrome trim, and a matching chrome clip. Engraved on the bottom of the cap, as well as on the nib, is the brand name Opus 88.

Qualities

The Opus 88 Koloro Fountain Pen is an eye-dropper only fountain pen. It has a large ink capacity of 2 ml. Each pen comes with a free, high-quality eyedropper. Due to the notoriety of leaking for eye-dropper fountain pens, there are a few features worth mentioning on the Koloro. First, there are two o-rings in the pen. There is one that resides behind the nib unit, and the other is just below the threads of the grip sections. These two o-rings help prevent possible leaks. Second, the Koloro also has a piston in the back connected to a rod inside the ink chamber. This piston can be unscrewed to allow air flow into the pen, to help prevent burping due to the transfer of heat from your hand. As well, the rod doubles as both an agitator and primer for the ink. This eye dropper design is found among high end pens and is one of the features that make the Opus 88 Koloro an excellent eye dropper pen.

Performance

With all of that said and done, the true test is still to be spoken of. For this review, we used a Blue Blue Opus 88 Koloro Fountain Pen with a Broad nib that one of our employees received for Christmas. We had him ink it up with Nagasawa Kobe Nada Brown Ink. During use, there were no issues with burping or any leakage. The nib was juicy and laid down a lot of ink, although, your experience may vary based on the nib size that you select. All in all, the Koloro gave a wonderful writing experience and was a joy to use.

Conclusion

If you’re new to fountain pens, or have been a user for too many years to mention, the Opus 88 Koloro Fountain Pen needs to be a part of your collection. Not only does it have an ingenious design, it’s also very affordable! Don’t forget to subscribe to our blog so that you don’t miss out on any new releases or giveaways!

That is one sharp looking pen. I’ve already read several reports on this incredible pen and would certainly like to own and write with one. Thank you so much for the opportunity.

As to what to review, I think it would be nice to review Waterman pens.

Thanks for the opportunity. I think you should review the Franklin-Christoph Model 31 Omnis. I received one for the holidays and I absolutely love it.

My favorite ink is a kind of troublesome ink at times but I use it anyway because I love the color and permanence of the ink, it’s Noodler’s 54th. It creeps all over my nibs, it widens every nib I use it with, yet, I continue to fill my pens with it.

I do have a few Eyedropper (ED) pens. And none of them have a piston arrangement at all. To agitate the ink, simply shake the whole pen. It has always worked nicely. So can you please shed some light on the need of piston/rod in an ED pen?

The ED that I have are few Platinum Preppy, Pilot ED Tank, ASA Nauka.

Hi There! The rod doubles as an agitator and a primer! With most c/c pens, you can squeeze the cartridge, or twist the converter, to push out a little ink through the feed to prime the pen. With eyedropper pens, gravity does all the work, and you have no way to prime the pen. The Koloro, however, uses the rod (with the vacuum that is created in the ink chamber, to be able to push a little ink out and prime the pen. Thus, it solves one disadvantage to using an ED pen.

When you are testing a pen/ink what do you like to put down on a sheet, looks like lines in different directions, ink splot, and some writing?
