Very disappointed in these. I purchased for presentation packets of less than 10 pages each. Box says they hold up to 20 pages. As soon as my audience opened the cover the spines came off. So embarrassing. I would not recommend these to anyone.
Needed these to put together a lesson for a youth class during a convention. I used the thicker copy paper from copies I made at Staples as opposed to copies I would make at home and only used 6 sheets including a cover but it held together pretty well. As you know the 9-11 age group may not be as careful with a folder as an adult. I didn't see any laying around later unattached. I would recommend this product even if it won't be filled to capacity.
Have used them before and the only problem I find is the plastic slides are really flimsy. Works for me as I use them for a two to three page appraisal. Anyone needing to put more papers in will be disappointed!!
These used to be good. However the quality has really gone downhill (way too slippery now). The slide grips came off all of my reports. They wouldn't stay on the edge. These were board packets so that was a little embarrassing.
