I think my search for perfect travel-friendly fiber-tip pen is over. It’s been over a year since I started to look for something that could replace my trusted Rapidograph.
The dream pen that draws in pitch black is Staedtler Lumocolor permanent universal pen. The funny part is that I found it while cleaning art supplies bough at the last super sale at University Art. Somehow I never gave it a try after purchasing.
The ink is so opaque that areas of flat black look completely even, no cross-hatch effect, no distinguishable pen strokes. I am very happy.
