INK SWAB: 177/365 – Noodler’s Dragon Catfish Green (Highlighter Ink) Posted on June 25, 2015 by Christine (Pentulant) Another ink made for highlighters from Noodler’s. I’ve not used this one other than to swab it, but the others I have work well. Side Note: Have you ever seen Catfish on MTV? I came across it one rainy day late last year and can’t look away now.
