These are great they have a non glare finish that is easy on the eyes. Eye are able to read at any angle.Product as described… fast delivery… does the job!… no problems!The sheet protectors are very good and a good value. They are clear and very thin. My preference: not quite so thin, and instead of completely clear, I prefer protectors that are slightly opaque, as they seem not to stick when trying to insert the paper sheets.Wish it had an indicator for top or bottom....or insertion end/closed end. So frustrating!I use these to put my quilt patterns in.They help keep them organized and neat.it is goodThey are not flimsy but they are advertised as heavy duty and I would say they are just shy of that. I haven't had them long enough to give a long term rating so I apologize if I am making assumptions based on touch. So far, they are working fine with no tears--1-2 pages per sheet.The first picture is of the product. The second is a thicker product from OfficeMax. The product should be thicker since the label said heavy-duty and they are not.These sheet protectors are consistent in size and quality. In the pack of 500, only 1 had to be discarded due to wrinkles. I chose this particular design as I like how the inner corner is trimmed off. They are clear and easy to read through. They do not have a scent of any kind, and are clean except for a few stray punched hole bits. The box comes with 5 packs of 100. This pack seems like a good value if you want to protect a lot of sheets.My only criticism is that when using them in a typical 3-ring binder, the top and bottom holes are a little too exact, making them a bit uncomfortably snug within the binder. This makes it a bit difficult to turn the pages. Perhaps they will stretch a little with use.You may find that when trying to load sheets into the protectors, the opening is stuck shut. This seems typical of sheet protectors and is a minor annoyance. To open the protector, just grasp the top between your thumbs and forefingers and slide apart in a shearing motion.Keep in mind that when you add protectors to your sheets, the stack will almost triple in size, and you may need to purchase a larger binder.Good price and some extra goodies, but if you want these as specimen crystal-clear protector sheets then go buy something else and more $. For storing some art and print work (for myself) - its fine. I just sadly find the plastic a little hazy. Not dirty, but it kind of feels that way compared to everything else I have - like some bubble marks etc. Years ago, they would all be clear or a slightly mottled plastic (no sheen), and mostly thicker. Now you never know what you will get unless you buy the super high-priced versions. Anyway - I would classify it as a lower end bec of the haziness. It's ok in thickness but not thick. You get the drift... if you need a lot sheets for some personal stuff it works - which is why I didn't send it back.I bought these a year ago. I am in Canada. Generally these are quite good. They are a bit cloudy compared to Staples brand. They are also slightly thinner. There was a lot of damaged sheets though. I ended up throwing out over 50 that had a deep crease through the middle of them.I originally bought these in February of 2021 for $40.99 plus tax. Shipping was covered by Amazon Prime.Today, I look up the exact same product, and it is $87.89. So it has more than doubled in price. Now I understand that the cost of shipping from China has increased substantially, but not to the point where it is doubling the price of a product this size.I have bought hundreds of page protectors over the years but never have a bought one that compares to this one. When I need more I will not buy this brand because of the price and quality of this product. You can only get 2 pages into each protector and if you are putting two pages of photo paper into one protector it ruins the paper because the protector is the same size as the paper 8 1/2 X 11. I had 40 pagers to put in protestors and it took me almost 1 hour to complete. Buying from Staples because they are cheaper and are a little wider than the 8 1/2 X 11 sheet of paper.Page protectors are pretty standard and there aren't a lot of variations, not a lot of room to mess up such a basic product.On the downside, they are very thin and less easy to use than a more heavy duty page protector.On the plus side, they are very thin and don't add a lot of bulk.I can't speak for long term durability but seriously, what are you expecting to do with them anyway?Overall, I can comfortably recommend this purchase.
