Customer Reviews
This is one of my favorite pens! It holds a ton of ink and looks great! I've had a shimmering ink in it for several months and have had no problems with it clogging or hard-starting. I may have to get another one! My only issue is the cap takes almost four complete turns to remove.

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”

Beautiful pen! Stub nib a little dry but with use should open up a bit.

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.

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!

Be warned, this pen is huge! I think its the biggest pen I own now. I love the ink capacity of this eyedropper pen, and the fact that I don't have to worry about burping with the stopper knob. Great looking pen too. I like that clear, partially frosted acrylic. The nib is great. A little dry right now, but maybe I just need to break it in or use a different ink. It's filled with KWZ Flame Red right now I think.

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.

This is my favorite pen. I now find excuses to write. Holds a ton of ink. Writes very smoothly. It's very wet so use a minimum of 41 lb paper with it. The pen is also very attractive and comfortable. It does not post, but it would be too large if it did anyway.

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.

I enjoy writing with this fountain pen more than I anticipated. I enjoy the simplicity of design and functionality. It is a wet writer. It dissembles and cleans up easily. I find myself looking forward to each and every writing and drawing experience, with the Opus 88 Koloro Demonstrator fountain pen.

The green one is closer to a blue green which I really like. The nib is as smooth as any high end expensive pen. The feel is great in my hands. My only issue with this or with the Opus 88 demonstrator is that it takes more than 3 rotations to remove the cap. This makes it hard to use for quick notations.

This Opus 88 Koloro Clear Demonstrator is a fantastic pen! It is a big pen, both in girth and length. It is quite comfortable, but I do have large hands and prefer larger pens (Pelikan M1000, Visconti Homo Sapiens, etc.). The pen fills easily, but I used a syringe to get by the rubber stopper. That stopper works wonderfully, by the way. I took this pen on a trip and it didn't spill or leak a drop on the plane. Other pens were not as well behaved. Make sure to loosen the top every once in a while to let the ink flow while writing.
The only down side is that the pen does NOT post. It wasn't designed for that as the body and cap are the same size. This makes for a striking visual effect, but the casualty is posting the cap. I prefer to have a posted pen (don't like to set the cap aside), but the Opus 88 is big enough that a posted cap would make it unwieldy.
I purchased the 1.5mm Stub Nib option, and it writes like it should. The German nib is a Jowo, I beleive, as it is nearly identical to a 1.5mm loose nib I purchased.
I love this pen and will keep it in the rotation of daily writers.

This is a very nice pen and a value for the money. I purchased with a replacement stub nib. It was a cheaper make of nib and I have had some problems with the writing with this nib. The nib that came with it a medium Opus was great. Nice sized pen too.

This is a lovely pen, and I really appreciate that it holds so much ink. It's beautifully finished and very nicely balanced. It's writing a bit dry just now (using the Colorverse ink that came with it) - sometimes skips a little bit. I'm still getting to know it.

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.
