(2nd edit: added some experiences after 2 days of use)
This is my new Omas fountain pen. I always wanted to have an Arco celluloid, but when I came across this pen I could not resist. Also, since I have the Omas Ogiva Vision with the broad gold coloured Omas nib, I wanted to have a medium two-tone big Omas nib. I read they have a rich flow and are superb, and I’m not disappointed in this. This pen is a real joy to write with. It has a rich flow (with the Parker Blue Black ink I used in this en so far) and a flexible nib. Not flexible in the old sense, but more what other people call springy (?).
The pen is made of marbled dark blue celluloid with gold trim. It has the Arte Italiane 12 faceted doric shape.
Cap
The cap closes with a little bit more than 2 turns, which is really a bit excessive for my taste. It means you need to turns on the cap and then you have the pen in your hand, often with the pen in the wrong orientation for immediate writing. So the pen need a little bit more handling to be handy for quick note taking. It is more a pen for the longer story writing.
Blowing into the cap gives the cap has no air leak. Which is good since this is probably the reason until now the nib has shown no signs of drying out in the cap. This is an annoying problem of my Ogiva Vision. Not so with the Paragon.
Clip
The clip has the roller at the end, which I really like. It gives the pen an easy roll-in, roll-out of your pocket while still having a good grip on your pocket to prevent accidental falling out of your pocket when you bent over to pick something up from the floor. (Yes, I once had a pen slip out of my pocket this way).
Nib
The nib is the large Omas two tone nib, with the superb ebonite feed below it. I really like the long slender toothed profile of the Omas ebonite feed. The nib is medium, which is a little broader than a Pelikan medium. But that is just right for my taste. As said before the nib has a rich flow.
When I got the pen, the pen was mint and un-inked. After filling the pen up it refused to write. The nib slit is wide, you can see trough it when there is no ink in the nib. I think that the ebonite feed needed to be saturated with ink before the ink flow is ok. After waiting 30 minutes for the ink to saturate the feed, the flow was perfect.
The nib however had a little bit of baby bottom problems, so I took the Mad Dutchman’s Mylar sheets and smoothed and polished the nib a little bit. With great success. The nib now starts immediate on contact with the paper, and there are no signs of bad starting or skipping. The nib glides silently over the paper.
Even after having the pen lying open on the table for about 20 minutes, the nib writes immediately when touching paper. The Parker Blue Black ink looks a little bit darker then usual in this case, but at least it will write!
It is really a joy to write with the pen.
Barrel
As said before the pen is the 12- faceted Arte Italiane doric shape, and I immediately liked it a lot. The pen will not roll over the table when put down.
The pen is piston filler. I did not measure the amount of ink which can be put in the pen. But as far as I can tell it is quit a lot and certainly enough for my use. And anyway, I like filling up a pen.
The filler operated a little bit heavy on the first try, but this was probably due to the fact the pen was uninked and dry. After the first fill the filler operated more smoothly.
Grip
The pen has a nice shaped grip on the section. I like the fanning out of the barrel towards the nib; it gives me a natural position to grip the pen. The cap threads on the section are above the grip. These threads are not a problem, at least for me since I hold the pen quit close to the nib when I write. This is not problem for me since the nib is large and thus gripping the pen on the section above the nib is natural for me. But even when gripping the pen on the threads does not feel uncomfortable due to the fact the threads are not sharp but rounded.
Data
The “Arte Italiana Collection” is a tribute to the original twelve faceted model designed by Armando Simoni in 1930, made with modern materials and finish. The design resembles a twelve sided Doric column, and provide a precise grip to enhance the pleasure of writing. The Arte Italiana Collection is the perfect combination of refinement and practicality. This model Paragon, is celluloid, is available in gold and high-tech finishing. Celluloid produced in blocks and then bars is used to make OMAS prestigious celluloid pens. Obtained from cellulose treated with camphor in an ether solution, OMAS celluloid is completely athermic. It is hygroscopic and therefore absorbs humidity from the air. This means that it is dimensionally unstable and subject to chromatic variation. These technical problems were brilliantly overcome by Armando Simoni, OMAS's founder in the 1930's. Simoni developed a unique manufacturing process, based on a special form of celluloid, cured in an oven to prepare it for machining. OMAS has jealously guarded this technique over the years and still uses it to produce OMAS pens today. Cellulose embodies all the qualities that make a fountain pen truly great: light weight, resilience, robustness, pleasant feel, shine and extraordinary combinations of color. The Greek key pattern band, the symbol of the company, in 18K gold filled. The nib is made from 18K gold with platinum inlay chiselled, M size. Piston filling. The fountain pen is new old stock, never used and never been inked or dipped; comes with it’s own black box, instruction manual and warranty card.

1th edit----------------------
Here are three additional pictures taken in plain daylight. I think they give a better impression of the colour of the pen.

2nd edit----------------------
After using the pen for 2 days I can add now that the inkflow is very consistent. And the pen writes allways, even when left uncapped for a longer time. I never before had a pen perform this good!
This for sure is my new favourite, surpassing my Stipula Nettuno Idra and Waterman Liaison with broad strokes . The pen is certainly not cheap, but then I got a lot of value for the money. Wonderfull shape and material, perfect craftmanship, superb ebonite feed and a great performing nib.
Ciao,
