Perle Noir is one of the most recommended and well reviewed black inks out there. When I bought this ink a few years ago, I was disappointed. It is not the blackest, not the smoothest, not the fastest drying ink, not an archival ink, not the cheapest. I decided to give it a second chance so I eyedropped a Preppy with it and filled a Lamy All-star. Over the past few days I have written many pages of work notes with the ink.

Quite wet, which makes drying time long (almost a minute) and there is some show-through even on quality paper. No feathering though and the shadowing is beautiful, clearly visible ...
