While the black micro pens, (Micron and Sakura are brands that I've used), work I don't like then as their colors are just too intense and for me they don't look good on the scrolls or book pages. I prefer to just paint them on with a brush, but instead of black I use a mix of gray, brown, and black, and it's also watered down. It gives a much more realistic look to the text and it fits the scale of the scrolls and books better.
