Thank you so very much! Well the inking pens I use are Sakura micron pens, and the markers are Prismacolor. You can find both in art stores like Michaels, A.C. Moore, or Hobby Lobby. Though there are websites that sell art supplies as well. Though I always buy my supplies in store, I have gotten markers from www.Michaels.com or Blick Art Materials: www.dickblick.comI did make an art materials guide a few years ago. I don't use Sharpies any more, but most of it is still the same I use now, if you want to see it:Some comparable markers are Copic markers (which are a bit more expensive), and Winsor & Newton which are slightly cheaper and fairly new (at least that I'm aware of).
