Noodler’s Waterproof black is my new favorite ink. I have tried many black inks. This one is very dark, consistent, and waterproof. It writes well on medium to high quality paper and doesn’t do too badly on cheap paper either. I write with a dip pen, and I value the smoothness and viscosity. I like good line width variation and this ink works perfectly for that.I also picked up Apache Sunset for the first time. It’s fun and beautiful, but don’t get it wet! Both are a delight.
