Sketching on my commute has been challenging. Trains are full and they move a lot. Well, using ink is even more challenging! Especially a pen brush, which has very little friction on the paper.
I had been under the impression that the Pentel Pocket Pen Brush had waterproof ink. But it melts with water! Don’t know if it happens when it hasn’t dried up completely, will have to do more testing.
This sketch was done with a Lamy Safari EF, Noodler’s Bulletproof Black and the Pentel Pocket Brush.
