I am extremely happy with my Diamine Ink. I have the 'Canalside' colour from the 160th Anniversary range. Using my TWSBI Eco with a fine nib it writes with an earthy, very dark green, which I love. No feathering and flows beautifully. The ink is touch dry within 10seconds, so I don't have to wait to close my journal. I also like that it's made down the road from me in Liverpool. The Journal Shop supplied me this substantial 75ml bottle at a very good price and shipped it within a few days. Presentation is really nice too and when it's finished, I'll want to repurpose the bottle to enjoy continued use. My favourite ink so I highly recommended.
