I already sought out a place to write a review and left a Zero Star review. These arrive but were unusable. The reason I bought through Staples was because I didn't think I could get a 100 pack locally. Turns out that after these arrived and would not open without a struggle. I spent ten minutes trying to open one to use. I gave up after damaging a second one trying to open it. It turns out that Wal~Mart does sell 100 packs. I drove to the local star bought a replacement that opened and I had my project completed in less time than it took to discover that the original order from Staples order was useless. It wasn't worth the time to figure out how to return. I just threw it away. I'll not purchase from Staples again.
These sheet protectors are the best I've found on the market because they are true to size and will easily fit standard letter size paper. Many other brands are cut just a little smaller and it's sometimes very difficult to slide paper into them but Staples brand protectors actually do accommodate letter size paper without having to crinkle or bend it. They understand that 8.5 x 11 means the inside dimensions have to be that size not the outside dimensions. For that reason alone these are the only sheet protectors I use.
My wife is a language teacher at the U.S. Department of State language school and these sheet protectors are what she uses to protect and organize class documents and their translations. They are exactly what she wants and she makes heavy use of them. And as the "house" brand they are a good value. I recommend them for anyone else who has similar needs to protect and organize sheet documents.
