Opus 88 Koloro Demonstrator Fountain Pens Reviews

I love this pen. The steel nib is very smooth, the pen is light weight, and with the right color in it (I used Diamine Antique Copper) it is beautiful to look at. Build quality is also exceptional. Would I like it to post? Sure, but it is not an issue because unposted the pen is large enough to not need posting. All in all a very nice pen for a reasonable price.

BIG Pen with Awesome Features! I was instantly impressed with how smooth this Fine nib was. Loved the fit and finish of the pen body, and the internal "stopper" piston is a great relief when you might want to carry this around on the daily but wonder if you'll find yourself with a cap full of ink!

The fine nib writes much like a TWSBI Diamond 580 BROAD. I was a little surprised by its flow--WET! I perhaps thought for some reason that the Fine nib would be, well, more fine :). But I absolutely love it.

Very impressed with this pen. I like it more than the Koloro in part because it has a larger #6 nib. The pen does not post which concerned me at first. I tend to post my pens mainly because I prefer larger pens and posting gives me a bit more to hold on to. But rest assured the pen is plenty large without the cap. Feels great to write with.

Let’s start with the bad stuff:

Okay, now that we have that out of the way...
The good stuff:
This pen looks amazing, the flow is wet but never leaky, the vacuum seal is great for travel, the clip slips easily over fabric but still holds tight, the nib writes smooth with no skips, the grip section is big and not slippery (my wife has small hands and still loves it).

I’ve had this pen for about 2 months and would recommend it to anyone!

I love, love, love this pen. It has turned into my EDC because it is a solid pen, bulk filler without the drips and drama. I swapped the nib for a titanium nim and this baby is my everything. I am a fiction writer and while I type a lot, handwriting is a daily activity for me for creative reasons.

This pen is solid and while large, it is very comfortable for me. I have smaller hands, 6" wrist even for a plus sized girl and my hand does not cramp with this pen like it does with other pens. The material is usually warm and comfortable feeling. The valve is exactly what I have been missing from every eyedropper pen I've tried. This seriously makes the word of difference for ink flow and no drips. It holds an ample amount of ink and I have nothing bad to say about this pen.

Fun fountain pen! Thanks, Ron, for the recommendation!

The Good: Looks great, especially with a barrel load of bright ink. Nib is buttery smooth, even on poor quality paper.
The Bad: Too big to be a pocket pen (although I knew that going in). 4 1/2 turns to get the cap off (also known before purchase). Nib seems to scratch up inner of cap (wasn't aware of that). Not a big deal, but such a pretty pen soon looks a little, well, used.

Overall, a great pen for the price, with fantastic service from Pen Chalet (Less than a week from placing order to inking up, all the way down here in Australia!!!)

After the first writing with this pen for an hour, I'm convinced that this is my next ‘on the go pen’.

Thank You, Everything is perfect!

I love this pen. It is a Japanese style ED with a shut off valve (similar to the Namiki Emperors but at a fraction of the price), so it holds a lot of ink and you can travel with it without worrying about leakage/burping. It uses a #6 Jowo nib which is very smooth (I got the fine nib) and should be exchangeable with other Jowo nibs (Edison, Goulet, etc.) It is a large pen, bigger than my Pelikan M800 but comfortable to use. The clear demonstrator design is fun too especially if you fill it with a colorful ink like Apache sunset.
