Opus 88 Koloro Eye Dropper Fountain Pen Blue
To fountain pen geeks, the words "Made in Taiwan" are coming to mean "Expect something special and unusual". And fountain pen geeks like unusual. Opus 88 have been manufacturing on behalf of other companies since 1988, but now they're designing and making their own pens, aiming them quite firmly at those of us who love fountain pens, and want something a bit different.
The Koloro is a medium-sized pen with a bit of stylish flair. The main barrel and part of the cap is translucent, letting you see the ink inside the barrel clearly - you won't run out of ink unexpectedly! It also gives you a view of the nib while the pen is capped. The blind cap and two parts of the cap are made from ebonite, giving a really different look. It has a subtle mottled pattern, giving a somewhat granite-like look, while the contrast in textures between the matt ebonite and glossy resin makes the pen more interestingly tactile to hold.
While the filling system used by these pens is not something new - far from it - it's rare in modern pens. They may look at first as if they're piston fillers, or perhaps vacuum fillers, but these are actually eyedropper pens. More specifically, they're of a type often known as 'Japanese Eyedroppers' (though these aren't Japanese). They don't draw ink up into the barrel themselves, you need to use an eyedropper (or syringe if you prefer) to get ink from the bottle to the pen barrel.
So why the piston-like mechanism? It's a valve, to seal off the ink supply just above the nib. Why? Well, for one thing, it makes the pens safer to carry, as only the ink that's already in the feed can leak into the cap if it gets shaken about. It can also be used to work around a common problem with eyedropper pens. With a lot of ink and air held directly in the barrel, as the heat from your hand warms up an eyedropper pen, they can push a bit of ink out through the feed, onto the page. It's not usually a problem when the pen is full, only when there's air in the barrel, but if it happens to be a problem for you, you can just keep the valve closed, only opening it to allow more ink to the feed as needed.
In use, you just need to unscrew the valve a little before you start a longer writing session, and tighten it back up for safety when you're done. And if you just need to make a quick note, the ink that's already in the feed should be plenty, so it doesn't slow you down.
Supplied in a gift box, with a glass eyedropper.
143mm long capped, 125mm uncapped, 162mm posted. 15mm wide, 10mm at grip. Weighs 22g. Cap takes around 3 complete turns to remove/tighten.
Orders placed before 3pm Monday to Friday will normally be sent out the same day.
