So typically I prefer the gel highlighters but I've been running into some problems with them depending on the type of paper I happen to be using. Since I have various projects going on, all of which seem to have a different type of paper, this has become problematic. When I saw these, I feel in love. Not only do they come in color, but the other side of all of them is the standard yellow. Just grabbing one gives you at least two color options, which may be all you need for a given project. However, if you do need more, the other colors are available.
So far I have not had any problem with these highlighters regardless of the type of paper I am using. This is a huge plus because when traveling, I try to minimize all the items that I take. I'm still working on that but this will be a huge help in that process. I'm very excited to see what other projects come up that I can use these highlighters for.
