What materials are not affected by the amount of pigment used?
MARKERS AND COLOR INKS are dye based, not pigment based so you won’t find a wide range of prices. Most are good quality. PENCILS, PENS, CHARCOALS – These remain fairly consistent in price and quality through all brands. Expect to pay over $1 for an artist grade drawing pencil and about half that amount for an Ebony pencil.
