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.

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.

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 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.

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.

At first glance the fountain pen is not impressive until it is filled with ink of choice and then it looks like a pretty magic wand. It holds a lot of ink! The nib writes smoothly out of the box. I’ve not had any issues subsequent to initial writing. Inks May stain the inside of the barrel.

Opus 88 Koloro Demonstrator Video



Video Script

This is the Opus 88 Koloro Demonstrator Fountain Pen. It comes in a brown cardboard sleeve with the Opus 88 logo embossed in gold on the top. That sleeve slides off and there is a black cardboard case for the pen. "Opus 88 Fine Writing Instruments" on the top corner as well as "Since 1977" at the bottom corner.

A magnetic catch here on the hinge of the lid of the case that opens up. Information about the Opus 88 included. It is an eye dropper pen, so included with the pen is one glass eye dropper. The eyedropper actually extends out, or slides back in to fit in the case. It's made of glass. It's not a plastic eyedropper so it's a quality eyedropper. And then, of course, we have the Opus 88 Koloro Demonstrator Fountain Pen. A little bit of an oversized pen, but a pretty good size. I like the design of it. It has a black clip on the pen. "Opus 88" is imprinted on the bottom of the cap, beautiful, clear resin on the pen. It is a machined pen, so the outer part of the pen has that glossy finish, and you can see the glossy finish on both the top and the bottom of the pen.

Inside of the pen, however, since it is machined, it gives you a little bit of a smokey look to the pen. It is not completely transparent, but a little opaque. It comes with a stainless steel German nib that has "Opus 88" engraved on it, and the feed on the back side. It is an eyedropper-style fountain pen, so you would unscrew the front section on the pen, and then with that eyedropper that is included, you would fill the ink into the barrel of the pen, and then reattach it. There's a small O-ring here to keep the ink from leaking out and keep the pen sealed. The backside of the pen will unscrew as well and it has a piston that runs through the center of the barrel of the pen. That piston is more to keep the ink agitated, or to burp the pen if you need to, but really it doesn't have any problems with burping or any issues with the pen. It's a great design. It has an eyedropper system that's found on a lot of high-end pens. So great design, beautiful pen. I love the black and the clear demonstrator design, or look of the pen.
