I'd give it a 3.5 star to be precise. I tried this ink with Speedball nibs, Deleter nibs and Nikko nibs on Deleter manga paper (135kg), Canson Mix Media sketch book (98lb), Canson marker paper (18lb), copy paper, and printer paper. This is what I liked and disliked about the ink: Liked: very dark, did not bleed, free flowing on all different paper kinds of paper Disliked: clogged nibs, dries very quick, does not handle pressure - makes line consistent for the most part Personally I really hated how it clogged the nibs. After one dip and swipe - bam, the ink already stuck onto the nib (because it dries so quickly). You'll have to wash your nib with soap every 3-4 dip which isn't convenient. Because it clogged nibs, it was hard to control line variation. Very light pressure gave medium lines (instead of thin) and meduim pressure gave very thick lines (instead of medium). I liked how it was dark and that the ink flowed easily on all the different types of paper I used but because of the inconvenient way to handle the nib and hard to control pressure, inking turned out to bumpy experience instead of peaceful, which earns a 3.5. I think I'll end up using this ink to color black areas instead. XD

This is the first ink I bought for drawing pro manga. I liked its bright finish and the fact of it drying really fast. However, this brings a problem which is it clogs nibs. After I had used my new nibs with this ink a couple of times, all of them were pretty broken and only allowed me to draw broad strikes, even with a Maru pen. Now, I use it to fill black areas with a paintbrush.
