I cannot get the box to open along its incomplete perforations. They just do not work. They are also not very reusable. . I liked the old-style packaging where the bags of 100 pages were held closed by two little strips of tape that I could cut thru neatly with a small scissors. The newer style with the strip of adhesive closing the length of the opening flap and remaining sticky and in the way after prying the bag open is more work to open and more dangerous because it sticks to and damages whatever the adhesive touches. . Is there an easy way to open a page protector and put a page into it? I haven't been able to do it. It usually takes me three or four attempts before I can get the front and back layers to stop clinging to each other and let me try to push something in; and then trying to get a full page into a page protector without wrinkling is difficult. . I do like these page protectors because loose leaf pages quickly get worn and dirty. . But the page protectors are so slippery that I have to put them in 3-ring binders to hold them. . Trying to stack them doesn't work.
Staples medium wight sheet protectors clear work great for what I use it protect documents. It is priced fairly for 200 sheets per box. I would purchase again and have purchased a box before.
I use them to protect and organize piano music. It is so easy to keep music clean and to turn pages as the plastic provides a stable place to grab for quick turns. I store them in a large 3 ring binder that sits safely on the piano rack.
