I have gotten a total of 3 of the 24 packs so total of 288 highlighters. In them there are 8 Blue highlighters in every 24 pack. All 24 Blue highlighters have been dried out. The other 5 colors work perfectly but not the blue. that is the color I really need and will need to look elsewhere for them. I'm nervous to keep buying them if every time the blue is dried out, everytime.
