Opus 88 Koloro-Anyone Tried One Yet?

I too think that the demonstrator is a great pen. Great ink capacity, nice design, and quite wet. The large size is very comfortable in my hands. A great value compared to other eyedropper style pens like the Edison Collier ... I still love my Collier.

Clear demonstrator looks really good especially with the frosted sections and black matte clip. Unfortunately, I had to return the pen before even inking it because the cap just kept squeaking during capping and uncapping. Not subtle, once-every-so-often, barely audible squeaks either. They were loud, cringe-worthy squeaks with every rotation of the cap, in and out. Squeak squeak squeak. Same thing with the knob on the barrel end. Couldn’t stand it. Maybe I just got a dud, but that pen needed some serious WD-40.

The squeak can be fixed with silicone grease. This is a common problem with the Opus 88. Once greased, you will never hear it again.

Ahhh, I see. It was my first Opus 88 pen, and I never had a pen squeak like that before. Felt like it was unacceptable for it to squeak like that out of the box.

Mine squeaks too, it squeaks when uncapping and capping and when working the blind cap. I chose not to be concerned by it, and I figured that the parts would "wear in" and indeed they are. This I believe is the result of the beautifully tight tolerance that Opus uses to machine their pens and I see it as a sign of quality, if annoying at first.

 

I do wonder just how well the rubber stopper will hold up over time- I can see that being the first failure point and I wonder how long it will last and how easily it can be repaired. That's me thinking lifecycle and far into the future of the pen.

 

I love this pen so much. The grip section gave me pause at first but with repeated use, it's now very comfortable and a favorite for sure.

A request.

 

Going forward, for clarity, perhaps we can use Koloro to refer to the original and Demonstrator to refer, obviously, to the subsequent Demonstrator. Easier to know which pen is being discussed, no?

This is true!

Update ... I snapped off the head of the plunger mechanism. I was able to glue it back carefully with some superglue. And, while that solved that problem, another screw mechanism within the body became unscrewed exposing some cork, but thankfully did not allow ink to come out. Also, the top of the pen seems quite leaky, despite the fact I used silcone grease on every thread that I though might need it.

My orange (kinda) Koloro arrived today. A very attractive pen, I must say. I just need to decide what ink to put in it......

 

pen_master - any clues on how you snapped the plunger mechanism? I want to try and avoid it!

I've found the Koloro to be a great little pen. Somewhat uninspiring nib but I think the smaller Franklin Christoph nibs will fit it. Mine squeaks too.

I forgot to screw the plunger back into the body when I was trying to unscrew the top of the pen to clean it. The bottom of my hand put too mush pressure on the cap and it snapped. Doh! Thankfully, the superglue has held ever since!

Intriguing. Thanks for the video reviews. Does anyone have any experience/thoughts on how this compares with, say, the Pineider Avatar as a daily writer? This and the Pineider are currently on my radar.
