a little stiff/difficult to open that will hopefully change with use. a little small (1")when actually used although it looked big enough when I was purchasing it. Would think about the 2" size for any long-term use but for short-term quick for small meeting attachments/presentation notes it is workable.
I have my students use these handy loose-leaf rings to keep all of their vocabulary flashcards together. They hole punch their flashcards (usually index cards) and use the rings to keep track of all their cards. When exams roll around the kids have their study cards all in one place.
