These are super high quality! I'm on my third box as I work on a large project that requires me to organize lots of loose sheets of photographs and I haven't had any issues! They are made a thicker plastic than most protectors, feel very sturdy, are super clear, and are very easy to use. I like the little slit at the top that makes it easier to line up paper and I appreciate that these really feel like they protect the things I put inside--the area where they slip into a binder also feels very sturdy and secure, so I haven't been afraid of them tearing. So far I've only tried to fit 2 sheets into each one, but they could definitely hold several sheets easily if you needed to fit an entire stapled document or something into one. If you watch amazon, you can usually snag a box of 200 for between 12-18 dollars which is like 6 to 9 cents per protector, and I think that's a great buy! These will probably be the only protectors I use in the future because I like them so much. In fact, they're actually a little too high quality for my needs, but I won't complain! Definitely a good product if you are willing to pay a little more and require something that can handle a bit of wear and tear.
