Let's take a look at how the ink behaves on fountain pen friendly papers: Rhodia, Tomoe River, and Leuchtturm.

*For my writing samples I use:

Water resistance: Medium

Feathering: None

Bleeding: None

Overall, I love this color. I do with the flow was just a little bit wetter, but I enjoyed it overall.
