if you decide to use a permanent marking pen, like sharpie, it will come off with alcohol, because the marker itself is alcohol-based. don't use other permanent markers that are solvent-based. the solvent you must use to remove the ink will probably cloud the clear whatever-you-use, and it is way stinkier than sharpies. all-in-all, i would go with the dry erase markers. just be careful not to slip off the side no matter what kind of writing instrument you use!
