I am very disappointed in my 4 color dry pencil marking pencils. The only one that works is the pink one. The blue, green, and yellow don't show enough to tell it's there, even when I try to go over and over it. So for the price, I feel it was very expensive for only one to work.
I really like these dry highlighters because they dont leak yet they have a nice color to them when using them in my Bible study. I like their quality and the way I can highlight the different topics different colors. This is a great kit to have. Only problem is they are a bit expensive however they last a long time (if you change the lead which you also have to buy) Good stuff!
