About the Opus 88 Koloro

The Opus 88 Koloro fountain pen comes with a perfect balance of ebonite and acrylic. The transparent barrel allows the ink level to be view-able at all times. Designed specifically as an eye dropper with a control knob and center bar inside the barrel to help control ink flow, this type of eye dropper system is only typically found among high end pens.

The Opus 88 fountain pen has been fitted with a German stainless steel nib for a great writing experience. Each pen comes with a small bulb eye dropper to fill the pen with 2ml of ink. Select the color combination that is right for you.

Exclusive for Pen Chalet within the US.

One of my favorite pens now. I ordered a F and find it to be a smooth writer (once I remembered to open the bottom nob a bit.) it’s also quite beautiful. Highly recommended.

My "Blue on Blue" Koloro is now my workhorse pen. It wrote reliably out of the box. But for my taste, it was quite dry. It has a Fine nib. So I adjusted the nub to be wetter and now it is very good. It draws a slightly wider line now because it is wetter. As it came it would have been very useful for writing small numbers or characters in small spaces - but ( do not need to do that. I have no complaints about the pen at all. I like the ease of filling and the large ink capacity. I especially like the way the valve knob screws into the barrel. I do not worry about wear at that point at all. I am using Noodler's 54th Massachusetts ink and it behaves very well. I plan to do some air travel soon and I will test the sealing ability. If all goes well, I will probably order another of these with a different color and a medium nib.

This pen is worth every penny—and a lot more. Its nib is exquisitely tuned and buttery smooth. It is perfectly proportioned and balanced with cap posted or not. The eye dropper filling system is quite easy to use and the pen holds a tremendous amount of ink. Inkflow, thanks to the piston actuator, is flawless. But for a slightly wiggly clip and a threaded cap that takes too many turns to open, this might be the perfect fountain pen. Plus it looks damn good.

I purchased the orange Koloro with a B nib. Wow, it writes beautifully and I'm very happy with my color choice. Fast shipping from Pen Chalet as always!
Thanks!

One of the most dependable eye droppers I have ever used. Opus 88 is making some great pens. Love this eye dropper concept they have developed.

Really like this pen. Smooth nib and holds a ton of ink. Starts right up with no skipping and feels good in the hand either posted or not! I will agree with others that you need to get used to the number of turns it takes to remove cap.

I own many eyedropper fountain pens, particularly ebonite, this combo of that material and acrylic grabbed my attention when I saw it. The pen feels great in the hand and is indeed a unique design,both aesthetically and functionally. Blurping is a common problem in eyedroppers, this pen uses a chamber rod to try and prevent that,so far it's worked. My greatest surprise has been the smoothness of the steel nib (a bold) all in all I'm a happy camper!

My first impression was that a #5 nib was too small for the size of the pen but given that I like to write small and draw small, but also like a bigger pen, this works really really well.

The material feels "rich" and reminds me of the Pelikan 215 material. It's kind of sticky grippy and I love that kind of acrylic for a pen body.

Being an eyedropper may lead to messy situations like micro droplets of ink flying around and on your cloths, just a little more car when filling the pen in comparison to a piston filler.

An excellent pen at a very fair price.

FAQs about the Opus 88 Koloro

Q:
Will the shut-off valve produce an air-tight seal for flying, like the Twsbi Vac700 or Conid Bulkfiller?
Asked on Apr 18 2018 by Eric
A:
According to Opus 88, yes the shut-off valve will produce an air-tight seal for flying.
Q:
Is that a #5 or #6 nib? Really curious. Thanks!
Asked on Nov 13 2017 by Frank
A:
The Opus 88 Koloro comes with a #5 nib.
Q:
Who makes the nib? Thanks.
Asked on Nov 11 2017 by Richard
A:
It is a German nib made by a company named “WIN” (Writing Instruments Network).
Q:
1. Does this pen post securely??
2. Where was the pen manufactured??
3. What is the UNPOSTED length of the pen, nib tip to back (or - is the pen long enough to write with unposted)???
Asked on Nov 10 2017 by Mark
A:
1. Yes the Opus 88 Koloro pen does post securely.
2. The pens are manufactured in Taiwan.
3. The unposted length without the cap on is 5 inches.
Q:
What is an eye dropper Pen? And won’t it leak all over the place?
Asked on Nov 10 2017 by Carter
A:
An eyedropper pen fills the entire body using a syringe or eye dropper. The advantage is that the pen holds more ink. Since it has been designed as an eyedropper it has o-rings to prevent leakage.
Q:
Can you tell me the diameter in grip section?
Thank you!
Asked on Nov 8 2017 by Jorge
A:
The section on the Opus 88 fountain pen is about .0375 inches at the narrowest point and about .4375 inches at the widest. The section is about 0.875 inches long.

Opus 88 Koloro Video



Video Script

This is the Opus 88 Koloro Fountain Pen. It comes in a brown cardboard sleeve, the Opus 88 logos embossed in gold on the top. That sleeve slides off and there is a black cardboard box for the pen. Once again the Opus 88 logo in white, since 1977 in the bottom corner. Hinge style lid that has a magnetic catch. Inside is information about Opus 88 and the Koloro pen. And since it is an eyedropper pen, there is an eyedropper that is included with the pen. The bulb syringe slides out to expose the glass portion. It is a glass eyedropper that allows you to fill the pen and of course, we have the Opus 88 Koloro Fountain Pen. It is made of resin on the transparent sections, this particular pen is actually filled with ink and you can see the ink level on the inside. You can also see through the cap and see the nib on the inside.

The other parts of the pen are made of ebonite, the tan parts of the pen, as happened to be the blue and tan version of the pen. The pen of course comes in different colors as well kind of accents that the pen make really nice. It is a lightweight pen with that looks really good.

The trim on the pens are a chrome color. There is a chrome ring with a chrome clip and a small chrome ring at the bottom of the pen. Also, at the bottom of the cap of the pen, "Opus 88" is engraved into the cap. That cap unscrews and is threaded. It can be posted on the end of the pen. It is a good-sized pen. It also has a matching resin section on the pen and comes with a stainless steel nib with Opus 88 engraved on it and feed on the backside.

To change the ink on the pen you would unscrew the section of the pen and then you can fill it with the eyedropper. This pen is specifically made as an eyedropper pen, so has a high-end eyedropper system. You can release the back-end of the pen and that allows air to flow through. It also has a small piston or shaft that allows you to burp the pen if you need to, but I've been writing with it for a while, I haven't had any issues at all with it. Great pen, beautiful design.
