I ordered manga pens, paper, and art boards ages ago from my local comic book shop. I'd given up actually getting them. But when I went to get my subservice (monthly comic subscriptions), there they were! The cool thing about the paper and art boards is that they come preprinted with rulers, print marks and cut marks in that light blue that won't show up when photocopied or scanned. It makes planning bleeds and multi-page images so much easier. Now all I need is to get the characters in my head on paper and get some story ideas for them. You know, the easy part. :D
Here's the company that makes the pens and paper. Their site also includes drawing tutorials and an online store. They have some great sets of colored pens that I would love to get.
