Pelikan Brilliant Black. A standard black ink that is a good bet if you have a wet writing pen or have to use poor quality paper. It has the nice quality of writing with a narrow line, which keeps your fine lines fine. It’s dependable, reasonably priced and has very decent water resistance. But it’s also a dry ink, so with a dry pen it can look gray.
An everyday ink? Absolutely, especially with wet pens or challenging paper.
