Excellent performer! This is Faber Castell’s version of medium blue. However, unlike a lot of competing inks, this one is archival (ISO 12757-2 certified) and therefore a superior ...view morechoice for business use or any other usage where waterproof and permanence is a consideration. I have found this ink to go on a bit on the wet side but it dries quickly. I’ve had no issues with feathering or bleed through even on inexpensive paper. The color is good, stands out well on the page. This is the ink that comes with Faber Castell pens in starter cartridge form. I’ve been so impressed, I just bought a bottle of it as this is now my go-to blue ink, replacing Waterman’s Serenity Blue which is a great ink but not at all waterproof. Very highly recommended. view less
