Heerlijke vulpen om mee te schrijven met een enorme inktcapaciteit.
Excellent value for money
The Koloro demonstrator is well built and well finished and writes like a charm. Filling the pen is straightforward with the eye dropper that came with it. The shut-off valve operates well and should provide protection against leakage when in flight.
All in all the pen provides excellent value for money and is hereby heartily recommended.
Opus 88 koloro writes like a dream, and is very beautiful. It was an excellent purchase. Fontoplumo as its best...
A beast of an eyedropper
This is a substantial pen and even with the fine nib I chose this is a very wet writer. I've seen a review that suggested it had the same feedback as a pencil but mine is nicely smooth. I filled it with SBRE Brown and got some nice shading on a Kokuyo Campus notebook.
It's definitely my largest pen to date but I have large hands so it is comfortable for me. While it feels suitably solid it isn't too heavy. Only time will tell if it turns out to remain comfortable for extended writing periods.
All the threads squeak at first and the plunger that seals the section from the body was quite stiff but a little silicone grease soon fixed all of these issues.
The worst part is the clip which I find to stiff and the matt finish does not look like it will last long. There again I can probably take some tension out of it and a little patina from use is, in my opinion, not unattractive and just shows that the pen is being put to good use.
It's early days but first impressions are very positive.
Great fountain pen
It is an excellent fountain pen. The quality of the materials is very good. The nib works very well, with no need for adjustments. It is more beautiful in the hand than in the photos. Superb value for money.
Buena capacidad de tinta. Diseño equilibrado.
Posibilidad de poner plumines #6 de titanio.
Muy contento con la compra.
With this gigantic barrel you will never again run out of ink! The eye dropper comes with a pipette, so you can immediately fill the belly of this whale of a pen. As usual, great service!
