Thanks so much! And not too expensive either. Definitely will be looking into these, as mine are starting to run a bit dry. :)
Thanks for the suggestion!
Keep in mind they are alcohol based, and work best with alcohol based fineliners and the like (Letraset sell them as well).
As for best paper I can't really say, these have bled right thru everything I've touched them with :P. Always have some card or plastic sheet under your paper so you don't mark your desk.
