I think Opus 88 makes some amazing pens. I have the Kolor Demonstrator in all the colors and 3 Clear Omars. Fantastic size to encourage a relaxed handgrip and a wonderfully tuned nib out of the box to boot. I have broad, medium, and fine nibs. I'm awaiting a stub.

Omar Demonstrator
Opus88 makes wonderful pens, the Omar Demonstartor
is no different. The sleek construction of the pen feels great in the hand. The eye dropper filler holds a generous amount of ink that doesn't run out quickly. And it writes like butter. What more can you ask for in a pen?

Koloro Demonstrator
I purchased this pen with a stub nib. The first one just didn't have great ink flow. It railroaded easily and had many hard starts. The replacement pen that Pen Chalet sent (super fast by the way) worked flawlessly out of the box. It is nice and wet and a very smooth writer once you become accustomed to a stub nib. I own many pens that are significantly more expensive, but this is one of my favorites to write with. The size is perfect for my hand. The nib makes my handwriting look better than it really is. One thing I learned is that you really do need some silicone grease where the feed screws into the section. There is a little o-ring in there, but it is not sufficient to prevent ink from flowing through the section around the outside of the feed and nib.

Medium nib is not too broad for my taste, and I'm usually a fine nib guy. Works great! Smooth writer. Nice ink capacity. Love the look too.

I absolutely LOVE this pen. It's girthy around the section, which I like, and the medium nib writes wonderfully.

I'm simply returning for a direct exchange due to a minor defect, but the customer service is second to none to get it sorted. I do all my shopping here.

Koloro Demonstrator
I am very happy with this pen. Bought it mostly for the appearance, but I love the filling system as well. The nib wrote well right out of the box. When I filled it for the first time the ink wouldn't flow to the nib, even after sitting for a good long time. After removing and rinsing with water, it flowed. Fairly wet but not a gusher.

Omar
I bought the Amber with 1.5mm stub and I love it! The Amber color is really nice looking. I personally like the contrast between the cap and barrel even though they are the same color (more or less). I also like the end finials in the ivory color. The nib is so smooth! Great writing experience out of the box. I inked it up with Diamine Ancient Copper; a really good match. The barrel holds plenty of ink even for use with the stub nib.

Definitely get it if you’ve been thinking about it.

This gigantic pen is a beauty to behold especially in the clear color. The look and feel of the plan is soft and understated and classy. It holds a tremendous amount of ink and the flow controller Is a definite plus. I would recommend this pen for anyone looking for a large large pen with a justified high price tag

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.

Koloro
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”

Koloro
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.

Koloro
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.

Koloro
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.

Koloro Demonstrator
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.
