I have about 6 of them and none of them work. The highlighter will not stay out. It goes back inside the barrel when I try to highlight. Totally useless. Maybe there is a way to lock it in place, but I have not been able to make them work.
I'm sorry but wasn't impressed by these. Had to rub several times to highlight and then it wasn't very 'dark'. Think I'll go back to what I was using. The 1st product I have ever had an issue with. Everything else was PERFECT. Service, everything! Just didn't like the pens themselves.
I only gave this markers a one, because I could not give them a zero. I found them to be unusable and call CBD and told them so. The crayon inside the markers would not stay out so I could use them, and they did not mark at all.
