Here's a quick list+review of my favorite sketching tools:Prismacolor Col Erase Pencils
Very nice colored pencils, I use them for outlining and sketching. You can get really cool effects if you use these to draw the outlines of a marker drawing.Pilot Color Eno
Good if you prefer mechanical pencils. A bit softer and smudgier than the Prismacolor ones, but pretty much the same thing.Pentel RSVP Pen
I use this for inking in my sketchbook. It's not water or copic-proof, but it works well and it's cheap.Canson Sketchpad
Good inexpensive sketchbooks, I use these for warm ups, gestures and thumbnail.Copic Sketch Markers
Expensive but worth it. They last pretty much forever as long as you don't break the plastic marker barrel. They do bleed through almost all papers though.
