This is a smooth writing ink that works as it should. The blue-black color is just right for business documents: it is distinct and easily findable among printed black text, but it doesn't contrast with black so much that your eyes automatically jump to it, making the black text difficult to concentrate on. This is the perfect color for signatures and notes, and is a subtle way to convey that what is written is original and not a (black and white) photocopy.The ink does not bleed or feather any more or less than any other fountain pen ink. As with all FP inks, the tendency to bleed is almost entirely determined by the pen nib and the paper used. It writes well, with minimal bleed-through on standard 20lb copy paper, making it useful for everyday business. It does tend to bleed through the thinner paper of legal pads, but it is fine for one-sided use.It is not a fast dry type, but with a fine or medium nib it dries quickly enough that it needs no blotting. The flow is smooth and consistent in all pens in which I have tried it.
