Hi,
Actually this post is a result of long term project. I was using my Senator Windsor (medium, neither wet nor dry) with different blue inks. And the notebook is Leuchtturm 1917. I hope it helps you to find your favorite blue ink.
(I just didn’t have Noodler’s Baystate Blue in bottle. It was a sample. Therefore, here you are a photo of Senator Windsor pen)
Which blue ink is your favorite? Or which blue ink you love the most, other than those?
Cheers
Zeynep Feelingtheblues
