Not bad but there are some areas needing improvement.

I Thought they would be not messy and quite elegant but the only color that I was pleased completely with is the yellow color. They weren't horrible but the green especially was very messy and didn't highlight without leaving a sticky residue. I would recommend them for the non-bleed through but they were not as high quality for the price.
After using these three gel highlighters in my journaling Bible, I ordered the larger pack. I've had no problems of any kind from using them. They go on dry with a slight waxy feel, but that disappears overnight leaving the highlighting undetectable to the touch. There has been no bleed-through and almost no ghosting in my ESV journaling Bible. The yellow is the lightest and most subtle of the three, but the print shows through all three colors.
I like them better than crayon or colored pencil, although those will work too. These and a 005 or 01 Pigma Micron pen are all I use now in my journaling Bible.
