Opus 88 Pens

One of my favorite pens. This nib is writes so silky smooth it's such a joy to write with.

Purchased the black unit. The pen is a little short in length when not capped, but this pen is such a joy to write with. Inked with Krishna Orchids (lovely ink), the pen writes smoothly and maintains an even ink flow. As for some eye-dropper and non-eye-dropper pens, this pen has not created one ink burp or mess at all. This is an eye-dropper pen that can be confidently taken to work or school and perform admirably. The small valve/screw at the back is a peace of mind safeguard for unwanted ink leaks in the cap... in my experience anyway.

Girthy, kind of unique visually. Holds a lot of ink. Fair price.

Really enjoy using these eyedropper pens. Recommend medium nib over fine nib. I now have four Opus 88 fountain pens and I am very satisfied with every one. The Fiesta pen clip when posted does tend to get in my way when writing. However, these are the only eyedroppers that I have never had the problem with burping and that means a lot to an eyedropper pen user.

Loving this pen. First one had issues, but the team changed it without any hassle. The replacement works like a champ: simple, direct, efficient, comfortable, smooth, and brightly colored. Highly recommended..

Ink capacity is great, the pen looks fantastic, and it is a nice size to hold.

I bought this to try Azizah's (of Gourmet Pens) "hack" of putting the Pilot Parallel nib on the Koloro Demonstrator. It is so much fun!

Very nice. Writes really smooth.

One of my favorite pens now. I ordered a F and find it to be a smooth writer (once I remembered to open the bottom nob a bit.) it’s also quite beautiful. Highly recommended.

This pen is just a fantastic writer. I ordered mine with a broad nib, and it's hands down the smoothest, juiciest pen in my collection. The stopper that regulates ink flow is a nice feature. At first I wasn't sure quite what I thought of it, but now that I've had a few weeks to write with it, I really like how I can reduce the wetness by closing it up if I'm using paper that can't quite withstand a big, broad, gushing nib. But with paper that can stand up to all that ink...it's a writing experience like none other. I wouldn't suggest this pen with a broad nib as an EDC, but for journaling it's wonderful. It's my first Opus 88 pen, but I'll definitely be buying more. I'd also like to add that Pen Chalet packaged it with care and shipped it to me faster than I expected. I was very please with all aspects of this purchase.

A solid and stout, well made pen. I went with a broad since this thing holds a massive quantity of ink. The nib is smooth as silk and flows fantastically, and you barely need to contact the paper. My only negatives are the fine threads on the cap which look nice, but it takes four and a quarter turns to remove. The threads on the stopper knob are also very fine and tedious to open, but you don't have to do it for shorter writing sessions. I also wish the black finish on the clip was glossy instead of a flat finish, but that's subjective. I recommend this for those who are into demonstrator style pens, or just larger pens.

Out of this world; writes like no other pen in my collection. Broad nib too wide for poor quality paper due to feathering of j herbin ink

My "Blue on Blue" Koloro is now my workhorse pen. It wrote reliably out of the box. But for my taste, it was quite dry. It has a Fine nib. So I adjusted the nub to be wetter and now it is very good. It draws a slightly wider line now because it is wetter. As it came it would have been very useful for writing small numbers or characters in small spaces - but ( do not need to do that. I have no complaints about the pen at all. I like the ease of filling and the large ink capacity. I especially like the way the valve knob screws into the barrel. I do not worry about wear at that point at all. I am using Noodler's 54th Massachusetts ink and it behaves very well. I plan to do some air travel soon and I will test the sealing ability. If all goes well, I will probably order another of these with a different color and a medium nib.

Love this pen. The nib is finer than a Western Fine which I really enjoy. The amount of ink it holds is amazing. The build quality is excellent. It is big but I love larger pens.

Love the pen. Absolutely Beautiful and an extremely smooth writer. Note to you all who will use the piston feature regularly to stop the flow of ink into the feed. In my experience with Organics studios inks, it takes 3-5 minutes for the ink to begin flowing again, which can be annoying if you want to write right way. I'd leave it "unstopped" if you plan on picking it up over and over throughout the day to write.

This is a wonderful pen!

It appears that the manufacturer has corrected one of the few complaints about the whole OPUS 88 line - the number of turns required to cap/uncap the pen. The pen I received has reduced the turns from 4 to 2. I assume this change will be standard from here on out. This makes an excellent pen even better.

Writes like a dream

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.

Nice, easy to use pen. Holds a lot of ink, easy to fill. Despite being stainless steel, smooth writing nib. I'd definitely recommend it.

The Opus Fantasia is a contemporary in appearance, albeit “funky” but more importantly she glides across the paper effortlessly.
Buy one or two!

This pen is worth every penny—and a lot more. Its nib is exquisitely tuned and buttery smooth. It is perfectly proportioned and balanced with cap posted or not. The eye dropper filling system is quite easy to use and the pen holds a tremendous amount of ink. Inkflow, thanks to the piston actuator, is flawless. But for a slightly wiggly clip and a threaded cap that takes too many turns to open, this might be the perfect fountain pen. Plus it looks damn good.

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.

I purchased the orange Koloro with a B nib. Wow, it writes beautifully and I'm very happy with my color choice. Fast shipping from Pen Chalet as always!
Thanks!

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.
