I used a set of Prismacolor Premier Pencils on my first coloring project. I was just getting started and chose them for the variety of colors available. They lay the coloring down beautifully, but I found it difficult to use them in the small detailed places. So, I went in search of a pen or marker that would give me smooth, bold colors with no bleed through and still be able to color small details.
That is how I discovered Staedtler Pens. Staedtler Triplus Fineliners come in a variety of colors and are ideal for coloring. These pens are long and narrow, with a triangular shape that many colorists find very comfortable to use. Staedtler Pens are extremely versatile and are a favorite among beginners and seasoned colorists alike.
