Kaweco Royal Blue is a blue ink that is similar to Waterman's Serenity Blue but exhibits more of a purple hue. It flows nicely from my Pelikan's italic nib and is neither too wet nor too dry. It has no odor to it (some inks do). The blue pops nicely on white paper but is more subdued on cream or other colors of paper.
This ink should be perfectly suitable for correspondence. I would feel comfortable using it in a business setting, but it might have too much purple in it for some tastes.
The ink does not exhibit any sheen, and the shading is minimal. With a fine point nib, the ink may be too light, but with wider nibs it has good saturation.
At $17.50 for 30ml on JetPens, this isn't the cheapest ink you can buy or the most expensive. If you like a blue ink with a purple cast to it, then this is a great choice. If, however, you prefer a truer blue or blue-black ink, then I would not recommend Royal Blue.
I prefer inks with a little more character--lots of saturation, shading, sheen, unique colors, etc. So, I doubt Kaweco Royal Blue will be in my regular rotation. But I'm impressed by its good flow and it behaves well.
