What's your pen of choice? It seems to handle wet media well and I'm in the market for some markers for doing wet media coloring.
I got a Platinum Carbon fountain pen with ink from the same brand, i've been using it on these for years & can confirm that its great waterproof ink !
I have a Platinum Preppy that I love for lettering stuff not done in dip pens, I like the quality even on one of the most entry level pens. Also I believe it is the same cartridge as my Kuretake brush pen so I could even simplify my pen-pack for things like cons.
