They are as advertised, a dry highlighter. They felt more as a grease pencil. They worked. They were visible. You had to color like a crayon to use. They had to be pushed back into the pencil body with your finger when through using them. The ink moved into the pencil body so you must continually stop and feed. Bible pages are thin and dont endure coloring like a crayon very well. I ended up purchasing another set of liquid non bleed through bible highlighters from a local book store.
