Brand: Opus 88


De Opus 88 Omar vulpen is een grote eyedropper vulpen met een piston afsluiter. De gekleurde barrel van de pen is doorschijnend, zodat het inktniveau goed te zien is. De dop is gemaakt van een ondoorzichtig edelhars met verschillende tinten van de kleur van de pen. De pen heeft een ivoor edelhars piston knob, een zilverkleurige clip en een roestvrijstalen #6 JoWo penpunt. De pen wordt geleverd met een glazen pipet om de vulpen met elke kleur inkt te kunnen vullen. Een eboniet zuiger en een rubberen sealing zorgen ervoor dat de feed volledig is gesloten ten opzichte van de barrel zodra deze is ingedrukt, hierdoor wordt het risico op lekkages en luchtbellen verkleint. Door de achterkant van de pen los te draaien en de staaf los te maken, wordt de inktstroom geopend en komt er meer inkt naar de penpunt. Om optimaal gebruik te maken van de indrukwekkende inktcapaciteit, laat dan tijdens het schrijven de piston afsluiter open staan.

    One of the major attractions towards their pens is their size. The fact that their ink well is massive is also a great feature. I don’t write as much, but just knowing I won’t be worried about refilling is actually something I take for granted in other pens.

    I have several Opus 88s and on the whole they’re brilliant for the price point. However some may require some silicone grease on the threads to get rid of the squeaking noises it produces when your turn said threads. I do wish they included a small batch though.

    Excelente pluma. Es ligera de peso pero de tamaño considerable. Una vez rellenada con el cuentagotas no hay que volver a preocuparse en mucho tiempo y al ser transparente siempre sabes el nivel de tinta que tiene.
    Está muy bien construida y se nota la calidad de los materiales. Appelboom realuzó el envío con toda rapidez y el paquete venía perfectamente embalado para evitar daños en el transporte. Muy bien. Muy recomendable. Calidad precio excelente.

    Extremely good looking pen. Writes like a charm.

    I love this pen. It is a great writer, well made, comfortable, and beautiful, especially when I see all that ink sloshing around when I write. I ordered it with the 1.5mm stub, which performs flawlessly. This is my first eye-dropper and I like its practicality. Beside the huge ink capacity, it is easy to clean and switch inks. The shutoff valve is also a great feature, preventing any burping of ink and helping to regulate flow. I am very happy to have this pen in my daily rotation and grateful for the excellent transaction with Appelboom. (I have already trusted them with my next pen order and expect more to follow. -Thank you!)

    The delivery to Perth (Western Australia) is as smooth as butter! DHL delivers to my doorstep, even on Sunday!

    The overall design of the pen goes far beyond its price. The only trade-off is that the flex EF nib is quite firm and needs more pressure in order to get the line variation. I’m comparing it to Pilot 823 FA, as it is my reference for flex nib. Other than that, it is a highly flexible pen using standard Jowo No. 6 nib.

    This is a reliable, and well-designed pen. Maybe you can only have one wish: to have the option of the golden nib or more nibs options.

    Opus 88 Omar is built very solidly. This won’t crack if you drop it accidentally unlike some other demo pens. Ink capacity is generous at around 3 ml and shut off valve makes controlling ink flow to the feed very convenient. Pen has got good girth and heft and is a pleasure to use. Ink sloshing inside the barrel looks wonderful. Appelboom as usual offers this at good price with fast delivery.

    A thoroughly enjoyable transaction, priced competitively, good personalised communication with prompt free postage, making Appelboom the ideal destination to purchase luxury pens. The pen has a very good build quality, can accommodate a wide range of nibs and is a must have for any collection!

    This fountain pen is a big surprise given the price-point!
    Very good quality and beautiful nib to write with. It has a certain softness and super smooth. Added bonus is that it works great with shimmer ink, does not get blocked or flow issues. Highly recommended for someone looking for a large pen at this price-value!

    An excellent pen with a smooth nib, Really like clear “demonstrator” pens so you can see the internals and the ink

    Very smooth for a steel nib! No hard restarts and very good ink flow! Extremely big ink capacity! High quality construction!
    And Mr Appelboom is just the best pen seller in Europe! I ordered my pen from Greece and I got it in my hands roughly within 18 hours from my order!!!

    Without going into the technicalities of the instrument, I would describe it as a Simple and Beautiful pen. I bought the Broad Nib and the immense writing pleasure it offered was sublime…a perfect everyday carry pen. This pen perfectly qualifies for an impulsive purchase.
    The packing was very good and the delivery was swift overall an excellent experience.

    I am surprised at how much I enjoy this pen. I never have hard starts, it always writes when I uncap it, and very nicely. It has a wet flow and the broad nib brings out shading beautifully. I’m not a huge fan of the look of the cap but I will probably buy another one of these just to keep 2 inked at the same time. One of my favourite pens I currently own.

    It’s a nice big eyedropper demonstrator with some tasteful frosted accents on the inside of the cap and barrel. Sports a dependable JoWo #6 nib, a large ink capacity(~3½ mL) for all you broad and/or wet nib aficionados and has a shut-off valve to keep all of it contained inside the pen instead of burping out into your pocket while you’re on the move.

    It can be disassembled entirely, apart from the rear seal; you would need a special tool or some dexterity with a pair of flathead screwdrivers to unscrew it, and probably quite a bit of force to break the sealant bond initially.

    The shape and especially the clip are a bit quirkier than most of their other designs, which I really enjoy. I already owned a Koloro Demonstrator(the Omar differs in shape, but both pens are otherwise identically constructed) and that pen has held up fantastically over the past few years with heavy daily use. The acrylics are very sturdy and Opus 88 are very helpful if you ever need help.

    The pen is big, I would say a little oversized, but very comfortable to use. It’s cool to see the ink inside. I bought it with a broad nib which writes more towards a medium. Also it was a little bit on the dry side but after a little tuning it works fine. Very happy with it.

    Large ink capacity in this eye-dropper demonstrator pen. The pen itself is large with a smooth steel nib. Nice that the ink colour and amount can easily be seen in the clear body. Shape of Omar is also nice. Shut off valve is a good feature.

    What a joy this pen is!
    It is a large fountain pen with a with a generous ink capacity. The proportions are all very well balanced and the nib looks very well when the pen is in use.
    The clear acrylic is well finished and is a delight to hold. The pen rests in the hand delightfully and the highly polished valve and cap finials contrast nicely with the slightly matt finish of the cap and barrel. And the curved lines of the design fit add a sensuousness to the pen.
    Finally there is the matt black clip and valve band. I like this very much.
    The overall design is minimalist plus in my mind.
    Currently I have this inked with Iroshizuku Ebisu and when the sun catches the pen it shines like some large sapphire on my desk.
    Writing with the pen is a joy. The broad nib is delightful on the page and I thoroughly enjoy the experience of using this masterfully crafted instrument.
    Regrets? Yes. I cannot afford to have an Opus 88 Omar for all the inks in the Iroshizuku range!

    The OPUS88 Omar is a big pen. Thanks to the form it works well to find a comfortable writing style with it. My first nib had a slight gripping problem, but after a replacement it’s a very nice pen. The pens volume and more "spherical" design makes it different to the Demo pens. I like this one a lot. Looks absolutely great and performs very well. It doesn’t post well, but I don’t think you will need that – unless you have truly huge hands. Only drawback is that the pen seems to be more prone to spill ink into the cap than the other OPUS88 pens I have had – but it might be the ink in this one.
