The ink is a dark blue with an undertone of purple. It has a very wet flow. My medium nib writes like a broad so I will probably restrict this ink to finer nibs.
On Midori MD paper, there is shading, sheen, no feathering and no bleedthrough.
This was written with a TWSBI ECO-T medium nib.
Below are a couple of photos of how it looks when it is written on both sides of the paper.
