Opus 88 Pens

I'm loving this pen, so beautiful, chunky but not too heavy. Looks great and writes wonderfully!

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 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.

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.

The green one is closer to a blue green which I really like. The nib is as smooth as any high end expensive pen. The feel is great in my hands. My only issue with this or with the Opus 88 demonstrator is that it takes more than 3 rotations to remove the cap. This makes it hard to use for quick notations.

This is an outstanding fountain pen for the price!!

The stunning appearance of this pen is surpassed only by its luscious feel. It is a beautiful writer and fits well in the hand.

I love this pen, but I wish I had purchased a fine. I did not anticipate how juicy the nib would be.

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.

This is a very nice pen and a value for the money. I purchased with a replacement stub nib. It was a cheaper make of nib and I have had some problems with the writing with this nib. The nib that came with it a medium Opus was great. Nice sized pen too.

The Picnic holds a lot of ink which works well with the broad nib in my pen.

Great pen, excellent service!!! This pen has that simple sophisticated look and feel. Lays down the ink nice and smooth

This is a lovely pen, and I really appreciate that it holds so much ink. It's beautifully finished and very nicely balanced. It's writing a bit dry just now (using the Colorverse ink that came with it) - sometimes skips a little bit. I'm still getting to know it.

I love this pen! The purple is a gorgeous shade and the writing is so smooth! This is my 2nd Opus and I know I'll be buying many more in the future!

This pen feels really nice in hand and the length is not too long for my small hands. The Ebonite parts feel warm and the filling mechanism is very easy to use. Nib is smooth as expected of JoWo nibs however it has more spring than my other pens with the same nib brand.

Beautifully crafted. Well balanced pleasure to use

I love how this pen writes and it holds a lot of ink. I would highly reccomend this pen!

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.
