The color of the highlighting itself was quite neon, which, for the most part, I liked. I am a purist when it comes to highlighters, so yellow is always my favorite color. One major factor I did not like about the highlighters was the way the waxy stick seemed to crumble as the pen moves across the page. This happens with crayons, and the younger audiences may not mind, but I do not want the crumbly bits to get stuck to other pages or make a mess of what I am working on. It seemed like this may not have happened as much with the yellow highlighter, and I actually enjoyed the yellow one quite a bit.
The highlighters do provide a great contrast with the letters on the page.
For a less common highlighter format, these were not bad, but I could not see myself buying them due to the issues with the crumbles going around the page. If you enjoy the colors, and you are not highlighting academic works, these very well work for you.
