I got a new pen - a Lamy Safari fountain pen - and have been trying it out with the standard blue ink cartridge it came with.
I have a converter I can use for my own ink, and want a permanent ink that I can also use with watercolour on top, but I'm a bit worried the pen will dry and clog. Do you have a fountain pen you use for drawing? Which kind of ink do you use in your pen? Will Indian ink ruin the pen? Please share your experiences in comments.
