By the company that makes the best colored pencils. I remember getting a huge set of these markers for Christmas when I was a kid and spending countless hours with my brothers making our own comics. Prismacolor makes also carries a TON of colors.
I JUST STARTED DOING TATTOOS AND WHEN I MEET ANYONE AND TELL THEM THEY START TELLING ME WHAT THEY WANT! THIS TIGO MINI SUEDE SKETCHBOOK WITH PENCILS IS A GREAT WAY TO PUT DOWN ON PAPER WHAT I PLAN TO PUT TO SKIN LATER!
Another great idea. A bone that your can write with and attach to your other bones.
