When choosing the best drawing supplies, you've gotta keep the end goal in mind. If you're drawing to think, you can use pretty much anything. If you're drawing to create great art, you've gotta use something that will last.

I've been using Prismacolor markers since high school. I never use them for live graphic recording, though. I have a special set of supplies set aside just for live graphic recording work. But I do use Prismacolor markers for studio work sometimes.

Prismacolor markers are art markers. You'll need to go to an art store to get them or order online. So they're more expensive than Crayola or Mr. Sketch markers. Way more expensive. But they do go on sale sometimes, usually around the start of the school year.  They occasionally offer pretty big rebates, too. And Prismacolor markers do last a long time.

I like the broad range of colors offered. Also, because they're permanent, they don't smear. You can color over things drawn with non-permament markers without smearing. And there's nothing worse than outlining a drawing only to have it smear when you color it in!

Unfortunately, they do bleed through paper. And they do smell a little. But they are nontoxic, so they're safe.
