The only draw back is taking the time to put them in a binder lining the holes up can be a pain but worth the finished result. These are very durable thick and do not rip easily.
I had to complete a very large portfolio for my graduate program and ran out of sheet protectors. I liked these that I bought at Staples much better than the ones I originally was using. I ended up removing the previous sheet protectors and completed the entire project using these sturdy page protectors. I will definitely buy these again.
We're fixing our house after a flood and have found these sheets necessary to put in order our clippings from magazines as well as photos of the projects along with the contractor's estimates plus my notes from phone conversations. The sheets are easy to fill and to pull things out of. I can't stack them outside of the binder though as they slide everywhere. There used to be a kind that didn't slip & slide so much but I can't find those any longer.
