I've been using these sheet protectors for years. As always very pleased. Now I know l can buy quantity ( was buy 100 package) I will do so. These are Great QUALITY.
Got these to use for music binders for accompanying church groups etc. Bare paper with reinforcements are sometimes slow to flip pages in a 3 ring binder. and will eventually rip through the reinforcements requiring more copying transferring written notes etc. Thought these would be a great answer. And they are until trying to flip the pages. They somehow like to slip out through the binders' rings. Almost every single page at least one hole (usually the top) will slip through mid-flip. My favorite is when flipping 100 pages at a time to get to a different piece. And depending on the mood ALL 100 pages will come out WITH THE BINDER RINGS IN CLOSED POSITION. and NO the holes are not ripped through. How is this happening? I've tried numerous brands of binders (staples avery etc) and it happens with them all. Ready to return them all... not worth my frustration or time to insert pages....
