Noodler's Ink

So for my birthday a while back I received a bottle of Noodler's Bulletproof Black Ink and a much discussed Lamy Safari fountain pen. I then did this quick sketch using both. I find I have trouble getting different line thicknesses with the Lamy but it also loosens me a up a bit too. I'll probably try again with it sometime but I can say for sure that I love my Lamy for everyday sorts of writing.
