OPUS 88 - Koloro Fountain Pen.
The Koloro fountain pen is available in four different colour: blue, orange, red and beige. Each is made not just of the usual translucent resin, but a generous helping of satin-finished ebonite in an accent shade.
Having the translucent resin portions of the pen allows you to see both your current ink level and your nib while capped.
Flat-top eyedropper-fill fountain pens with a #5 Jowo steel nib, made of ebonite and resin.
The pen can be filled with the included glass eyedropper and holds 2.14ml of your favorite ink.
The traditional eyedropper pen has an ingenious system for releasing the shut-off valve. An ebonite piston and rubber gasket seals the feed off from the barrel when fully depressed, reducing the risk of leakage and burping.
The Opus 88 logo is very neatly engraved into the cap.
The box contains a simple rubber-and-glass pipette, which you use to drip ink directly into the pen barrel, from the section end.
