These sheet protectors keep my reports clean that I have to mail out. I even keep my unit phone directory in one beside my phone. I use them at home in my file cabinet to protect important documents. They have so many other uses! A great product!
For me, it's a pain to load pages into these sheet protectors - the opening seems to always want to shut itself (static). But it's worth the effort for the fact that these sheets take dry erase markers well, and wax markers even better. Many, many times it's handy to add notes to documents which I'd otherwise want to remain pristine - and these sheets offer that option.
