These are a great value for the money and a great product. the 3-holes are reinforced to not tear, the sheets have an opening that is easy to slide letter sized paper inside. (They do lose their sheerness over time especially when handled a lot with dirty hands.)
I use these to protect pages in a 3-ring binder - a daily journal, for posterity sake. These are durable, clear, and in a box of 200, a good value. I have been using these sheet protectors for 20 years.
