I found them hard to open but I learned after a while how to open them quicker. Otherwise they are OK. I am taking an on-line computer class and put the information in a 3-ring binder with the sheet protectors.
Was kind of disappointed because the pictures were not centered and a lot were cut off I believe that the margin should have been removed the girl behind the counter did then behind the counter because I wasn't sure how to connect my phone to printer to do them myself.
