Fine liners must be bleed proof. They come in many forms and brands. You must choose one that you love to work with. It is your detailer and your contour line.

I love to use 2mm mechanical pencils. Other artist prefer to use .05 mm leads because it give you a finer line. regardless you do need a pencil of your choice to do some under drawing that after the drawing is inked you can easily erase.

Get an eraser that works for you. I like the rubber kind and the eraser tubes that go in holders for detailed and tights spots. You are the artist you decide.

When applying white high lights to a drawing, I find it is easier to put them on at the end. Your white pencil crayon, white out pens and poster paint makers are ideal for this kind of thing, because the are opaque. Also get a black pencil crayon.

4 Big Chunky markers are needed for cover large areas in specific tonal values. These markers are transparent. Like watercolours you see through them. Four vales are needed. 1. a Light 30% 2. A Shadow 50% 3. A Core Shadow 70% 5. A Cast Shadow 100%

Chartpak are my choice for broad and fine line colour markers.

Not essential but a great addition CARAN D'ACHE water soluble crayons. These can be used with water brushes for bigger areas and deepening highlights and shadows.

Use softcore coloured pencils. they are better for quick, single stroke application.

We use rulers for more than just measuring. I prefer a grade school ruler because of it's feel in my hands. When I want to draw a straight line with a brush, a shaped ruler that is raised acts as a great bridge for detailing with a brush.

A palm sized set square with a raised edge. A raised edge prevents markers from smearing.

A Translucent bond pad 14x17 inches. A good size for drawing comfortable and doing a lot on one page.
