Opus 88 is a thing of beauty.

This is just a beautiful fountain pen for a beginner.
It’s not that cheap, but after buying 2 pens in the under $100 price range, I went up a little and was not disappointed.
The ebonite and arcylic blue complement each mother nicely. It looks rich and classy, without being too bold.
Once the feeder is saturated, writing with this style of pen is quick and easy, contrary to what you might see online.
I’m looking at buying more Opus pens already.
The medium nib that I ordered with it is smooth and beautifully designed and completes my collection of nibs and fill styles, for now :D
You will not regret the choice.
Lots of ink, secure and beautiful.
Be sure to lightly lubricate the threads to get rid of the squeak.
I used Super Lube 21030. Multi purpose synthetic grease.

I’ve been waiting for a pen like this for quite some time. Despite is bulky dimensions, it’s quite beautiful and feels good in the hand. The nib is smooth and flexible and the ink capacity is the largest of all my pens.
Best of all, it’s an excellent pen to travel with. The shut-off to the feed prevents any unpleasant leaks.
I recommend this pen highly - what a great deal.
And, as always, the pen arrived promptly and immaculately packaged.

I'm really enjoying this pen. The nib is smooth and the feed is nice and wet. I'm also enjoying the shutoff feature on this pen. I've flown with it twice now and no unpleasant accidents. I can't recommend this pen more highly.
Did I mention I'm enjoying it?

This pen is fantastic value, looks great, and as an eyedropper has huge ink capacity. The nib felt smooth out of the box, and writes wet, so it deserves an interesting ink selection.
Have to mention the excellent service from Appelboom too. They were friendly and quick to respond, swapping out a fine nib for a medium when I had a post-order change of mind (after I realised that these no.5 nibs would run a point finer than the no.6 in my TWSBI 580). Highly recommend both the pen and Appelboom!

My first Opus 88 and first pen with this kind of eyedropper valve, and an instant favorite. The ink capacity is enormous, and the flow has been great without opening the valve for a few quick notes, and with valve open it keeps up for pages and pages. The Fine nib has the smallest note of feedback and is on the wet side while still keeping a nice crisp line. Absolutely love it.

Goede pen

een fijne pen met een groot inktreservoir. Penpunt is ietwat stroef in vergelijking met de edelmetalen nibs maar voor deze prijs een echte aanrader. Vullen gaat gemakkelijk en zonder al te veel geknoei.
bedankt Appelboom voor de accurate verzending, bovendien nog feestelijk ingepakt. Compliment!

Gevoel van vakmanschap als je schrijft
- Review Add on: 29-01-2023

Alle technische voordelen zijn in de vorige beoordelingen al beschreven, dus daar ga ik het niet over hebben. Je moet deze pen niet vergelijken met bijvoorbeeld Montegrappa's en andere high-end pennen. Maar daar is de prijs ook naar.
Wat wel heel belangrijk is het gevoel die de pen je geeft als je hem gebruikt. Geen moderne fratsen als plastic cartridges, die overigens handig zijn, maar voordat je schrijft de pen vullen met een naald of pipet. je ziet de pen zichzelf vullen. Vervolgens geeft het schrijven een gevoel dat je met een ambachtelijk schrijfinstrument werkt. Bij mij zit de waardering dus in de emotie bij het schrijven. Een echte aanrader voor de echte schrijvers!!!!!!!!

A really nice pen

I really like the appearance and feel of this pen. It's not too big or too small. The shut-off valve lets me take it to the mountains without leaking. I got it with the stub nib which has some feedback, but gives nice line variation.

The Koloro is a nicely made, well proportioned pen with excellent materials quality and great fit & finish. The styling is unique and in my opinion rather attractive.
An interchangeable nib with a standardized base is a nice touch, as is the fact that the cap can be posted while the ink valve is open.
Writing manners are just fine, with good ink flow, a smooth nib and just enough bounce to be more expressive than a fully rigid unit.
My one criticism, is that the ink shutoff valve has a rubber face, which means that it compresses a fair amount when closing and thus requires an extra half turn or so of the shutoff knob in order to be in the "open" position.
Dankon, Opus 88!

I really like this pen! It's a wet nib but perfectly secured by this eyedropper-system.
A fountainpen for everyday, but special.
