I would expect nothing short of perfection from a world-renowned ink maker. What I didn't expect was a highly-saturated ink with a relatively quick dry time (6-7 seconds, max, even on coated paper), and bright, clear color that isn't garish. There is a depth and shading to this ink that reminds me of watercolors and makes me want to fingerpaint with it (and I may try it!). My best description is that it reminds me of a calm, tropical sea, with subtle variations that occur even with a fine, steel nib.
Oh, yeah, and on top of everything else, it's VERY colorfast. When dry, I get barely a streak with a wet finger drawn across the page.
I'm very impressed and will be buying more from this line. Beautiful!
