Reddit reviews Speedball Lettering & Drawing Round Pen Nibs B Style assorted,Multi,set of 6

This is a good set from Speedball on Amazon. The B5 is pretty thick and commonly used amongst traditional flash painters. Sailor Jerry used a Speedball B5 nib. I prefer the smaller tips, but they require some practice to get clean lines.

This is the ink I use with it. Super black and waterproof so your watercolor won’t smear it. Dip straight in the bottle.

The key with getting consistent lines with nibs is keeping your pen in hand at a steady 45 degree angle, and moving your arm, not so much wrist and keeping consistent pressure. There’s instructions that come with the pen set. They’re short, but useful. Read it. And of course, practice a bunch and you’ll get it.

Let me know if you have any questions.
