Opus 88 Koloro Demonstrator 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.

This is a “semi” tank of a pen, I don’t have any other pen this big in ink capacity or size. The jowo nib is ok but I prefer the “black bock” nib that I also bought here, l just replaced the feeder holder and that was it! Now it writes like a champ, I love it! Thank you much Pen Chalet for your service. You are awesome ????

This is a huge pen. I wish I had recognized how large it was before I purchased it. But that is my fault. Otherwise it is attractive.

I’ve never really been obsessed with demonstrators; I don’t hate them, but they’ve always felt like a bit of a gimmick. That being said, as soon as I saw this pen, I knew that I wanted it and I’ve been extremely happy with the purchase. I love the large size, simple but distinctive cylinder shape, and the absurd amount of ink that it holds. It’s not perfect; the eye dropper filing system is more involved than a simple cartridge converter or piston filler (I didn’t have an eye dropper pen, so that was part of the appeal for me), it tends to burp a little ink into the cap no matter how careful you are, and it’s definitely not a great pen for jotting quick notes. Still, it’s comfortable to hold, writes forever, and the fine #6 JoWo nib on mine is near perfection (smooth and wet with barely any feedback).

First, Pen Chalet customer service is AWESOME!

If you haven't had a Koloro Demo before, don't hesitate to buy this pen. I did extensive research to find a demonstrator pen that can hold the most ink possible. This is it.

It writes better than I expected. I am very happy with the purchase.

I really am enjoying this pen. Shows the ink very well which is the wonderful thing about demonstrators. And the ink capacity is tremendous! The nib writes very well - thank you for checking it out before sending it. All in all, a very satisfying pen purchase.

Love this pen. The stub nib is juicy and writes smoothly. The lock down option makes is a great traveler. Also pluses are the clean, classic look and ink capacity. Not postable, if that’s a consideration.

Pretty nice fountain pen with good, wet writing nib. Please note that this is big pen, so the functionality of it depends of how big hand you have. Grip could be just a little bit more thin to make it perfect.
