OKay here's some advice i come from a third world country and that would be South Africa and the Pantone markers weren't available here at that stage so I bought crappy pens but now I had to buy the real Pantone ones because there almost the best, so buy them i would recommend it.For just drawing simple lines use PILOT G-TEC pens use 0.3 0.4 0.5 and whatever you want to use and also some other pens that are thicker (go to www.artbyfeng.com and checkthe things he uses I mainly use his stuff) hope that helps.:cool:
