I use Sharpies. Shapies come in the standard "fat" tip, but also come in a very pointed super thin diameter. These work well because there is never enough ink to bleed out that fast. I also use the "side" of the point (on the fat tips), if it fits, and roll the pen, I do not press down on the edge, l just let it soak up a tiny bit. If you are having real problems, you could seal the edge with a tiny big of adhesive. This will block the coloring from bleeding through.
