Diamine Eau de Nil is a medium teal colour ink that leans more blue than green. It has an average flow.
On Rhodia paper, there is shading and no sheen. There is a little feathering and a little bleedthrough.
This is 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.
