This ink is a consistent high performer. The flow is good, I’ve experienced no issues with feathering or bleed through. It goes on a bit wet, but dries quickly. Of particular inter...view moreest is the archival rating of this ink (ISO 12757-2 certified) so you can use it for signatures and other business uses. I’ve used it in several different pens, ranging from European mediums to Japanese extra fine. My experience is that the color works better in the broader nib. I say that because the color is not as saturated as some brands cyan-turquoise inks. I have also found that Graf Von Faber Castell inks usually look better, with richer colors, if you wait 24-36 hours after inking them. I have no idea why this happens, but I’ve seen it enough to rely on. I recommend this ink for someone who wants to break out of the usual pattern of blacks and dark blues. I gave 4 stars not 5 solely because the ink isn’t as opaque as some other brands I’ve used in this color range. However, those inks weren’t waterproof, so on balance I consider this ink a better choice. view less
