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 have really enjoyed this pen. It is very lightweight, but is a good size and has a nice feel. Impressed by how smooth the medium nib I ordered is, and how the line is just right — not too wide, not too narrow. It is among the 1-2 best steel nib pens I own. Surprised Opus isn't talked about more. I got it on sale, and it was well worth. Also, holds a ton of ink.

I do like the dedicated eyedropper concept with the release valve. It works rather better than my attempts at "eyedroppering" cartridge pens. This is a good pen, if a bit on the large size for my personal taste. Unfortunately, I think the fine nib on this was a poor choice for me. It seems more like an extra fine, and is a bit of a dry writer. I later got the Opus 88 Picnic model with a medium nib, which is more like what I would consider an actual fine, and suits me much better.

The filling system is intriguing, but if you like to post the cap of your pen, you may find this one too top heavy. The sections don't fit well together. The pen is overpriced for its level of quality.

I love the size and look of the Koloro, however, the nib is scratchy. I had to smooth the nib on a fine nail/file buffer. Also this pen is a poor starter. I have to dip the nib in water several times to get the ink to flow consistently. I expected a lot more since this pen costs $75.00 on sale. Somewhat disappointed. I won't be buying another OPUS 88 product.

While I have converted other pens to eye droppers, this is the first one I have owned that fills this way exclusively. The steel F nib is quite smooth, and I like the shutoff function to prevent “burping”

This pen is well built for the great price I paid for it. I got the yellow/orange version, which wasn't exactly the color I had expected but it's nice in a quirky way. (The yellow is more green than I expected.) It holds a ton of ink and the nib is quite smooth. However, I did immediately swap it out for a stub Jowo nib and housing that I had on hand, which was very easy to do. The flow is wet (which I like for stub nibs) as long as I remember to open up the stopper. This mechanism does its job in preventing burping, a common issue with eyedropper fillers. I had my pen roll in a car on a road trip and in the end, all the other eyedropper filled pens leaked a bit, but the Koloro was clean as can be. The ebonite does have a rather peculiar smell... like vitamins. Not terrible, just a little odd.

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.

FAQs about the Opus 88 Koloro

Q:

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.
