Although there exists already a review for Herbin's Perle Noire, I want to add mine. Recently I bought a 1930s Sheaffer Lifetime Balance in black and I thought a black ink would really go well with it. Hence I searched a review for this ink here and found one here.
I very much like the thickness of the ink and I find it to be very strong. Like many Sheaffer pens, the nib is rather rigid than flexible but the ink runs very smoothly and almost lubricates the writing process. When I did the test with cotton swab, I was pleasantly surprised that the ink dries very fast. I intentionally used a rather cheap paper but it doesn't feather or bleed through (maybe the paper isn't so bad after all). Both the pen and the ink fare well on Moleskin paper although there is a bit of bleeding which is rather due to the nib than the ink.
Well, here you go and see for yourself. Please, excuse me for spelling Perle Noire incorrectly in the scan - I was rushed and when I realized my mistake I was too lazy to re-do my test and scan.

If you have further questions, please, ask.
