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.

I will say that overall this is a pretty nice pen. The build quality and detailing is quite nice -- on par with higher-end TWSBI pens, for example. It has a very satisfyingly solid feel to it, and some heft, too, which I personally like. The styling is nice, too. Some thought went into the design.

The nib on my pen came with tines misaligned enough to make line quality pretty badly off. It was a minor issue to correct, however, and once I did that things improved quite a bit. It also took some time and effort to get the ink flow adjusted properly. The way the pen works, you open the stopper valve by a bit when you want to write. I learned quickly that if you open it too far you get a ridiculously wet ink flow; not enough, and the pen gets rather scratchy pretty quickly.

On that latter point, my experience thus far is that the pen is prone to more hard starts than I'd like -- more than most of the other higher-end pens I own. I'm not sure if that's me not using the pen correctly, but I kinda doubt it.

I'm not displeased with the pen. It does put-down a very nice line, although I'd rate the Jowo F nib to be more like an M -- I wish it came in EF. I am ordering a Goulet EF nib to try with it.

I do think I'd recommend this as a fun little pen to try. I've been enjoying it, and it seems to have found a spot in regular rotation with my daily writing.

These pens are really nice. Nibs are smooth, flow is great, the choice of color combinations of acrylic and ebonite seem odd at first but are quite sophisticated. Workmanship is superb - amazing pen at this price!

I bought this for my husband who is a pen nut. He loves it. HE SAID: Modern look. Feels solid in build. I like being able to see the ink level through the body. Good grip. Weight is balanced with and without posting cap on the back. Medium nib creates good line variance. Ink doesn't dry out.

I purchased the blue Koloro (and ordered the corresponding Colorverse "Depth" ink with it), and I have been very happy with it. It took a little while to get used to the filling style and how it effects the overall flow, but once I had a good feel for it, the Koloro became one of my main, go-to pens.
I really really like ebonite, and it looks and feels great here. My only complaints are that I'd prefer if the grip were made of ebonite too, and the 3+ turns to uncap it is a bit excessive.
Also, one day I forgot to close the plunger before putting the pen in my pocket, and the endcap/piston-knob broke off! I know I know - I'm a total bonehead for doing this, but I wish it had been a little more resistant :\ I was able to superglue it back on, and it works (and looks) perfectly again... but secretly I feel a little dirty knowing there's glue in there holding it together. Oh well what can ya do. Nothing I guess.

This pen feels really nice in hand and the length is not too long for my small hands. The Ebonite parts feel warm and the filling mechanism is very easy to use. Nib is smooth as expected of JoWo nibs however it has more spring than my other pens with the same nib brand.

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.

FAQs about the Opus 88 Koloro

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:

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.
