The Opus 88 Koloro Black Fountain pen is a specific model of fountain pen manufactured by Opus 88, a well-known Taiwanese pen brand. The "Koloro" line of fountain pens is known for its unique design, quality craftsmanship, and smooth writing experience. It's features a flat-shape design with an interesting contrast between the satin body and the marbled colored details. The transparent material of pen body shows the filling mechanism as well as the ink level. Opus 88 Koloro is equipped by a #5 steel nib and fills ink via an eyedropper mechanism. Opus 88 eyedropper filling system has a large ink capacity and a valve to open and close the ink flow. Open the valve when you need to write for long sessions and close it when you want to carry the fountain pen in your bag (or for example on flight!).
To fill, Unscrew the barrel of the pen from the grip section. Take an eyedropper and fill it with your preferred ink. Slowly drop the ink into the barrel of the pen until it is about 3/4 full. Be careful not to overfill the pen, as this can cause leaks. Screw the barrel back onto the grip section, making sure it is tightened securely. Hold the pen nib down and turn the filling knob at the end of the barrel counterclockwise to release the air inside. Turn the knob back clockwise to fill the pen with ink. Continue turning the knob clockwise until it stops, indicating that the pen is full. Wipe any excess ink off the nib and feed with a cloth or tissue. Screw the cap back onto the pen and start writing!

Parker Premium IM Retuals Green Gradient GT Fountain Pen
First scented ink for me and it really put to shame the next ones I got. Has the smell of Kopiko sweet. This has a very pronounced and bold smell unlike other perfumed inks that has a faint mild smell. Really made my room smell like coffee when I accidentally spilled most of the ink of a full bottle. But I ordered another immediately as the ink was that good.
Coming to the color of the ink It has a nice dark brown color with some shading as well. No Sheen observed in TR68 paper. The ink isn't that dry but not very free flowing either. There's some viscosity to the ink. Not sure how it would perform on a dry feeding Pen. But this ink really deserves a wet medium to broad nib to put down that much ink to make the room smell nice as well as see the shading of the ink.
Genuine product , good customer service !
EF is too fine tbh , if you are considering a nib size for daily use , exams or to see the rich colour of your ink go for fine
