Question

For a permament ink that will write on almost any surface, use the Sanford Sharpie brand. It comes in various point sizes and colors. For wide lines, use the chisel-point Marks-A-Lot (made by Dennison)

For erasable whiteboard pens, use Sanford "Dry Erase"

For highlighter pens you can see through. Use Sand=ford "Major Accent".

For a list of these and other varieties varieties, see http://doitbest.com/shop/dept.asp?dept_id=2602

As for how they are made, that information is proprietary.
