I think these are really cool! I tried with gel pens and there were 2 issues. First, it didn't dry so was smearing all over. Second, the tips of the gel pens indent into the folders surface. That can't be erased so it will get annoying to reuse the folder. I tried wet erase pens and it dried quickly and was also more bold. I definitely suggest using some EXPO Vis-a-vis markers.
