Very sturdy. Really like them.Easy to useUse these dividers for my genealogy work. I put printed copies of documents inside sheet protectors. However, standard paper dividers used to separate each name get lost between the pages so I can not easily find where one section stops and another starts. These dividers are the same size as the sheet protectors. Stick out further then the paper ones so it is easy to go between sections. Works great. No problems with clarity. Just wish a little cheaper as I have ordered quite a few sets. Don't know how sturdy because I just starting using them and they are not used on a daily basis. But, I have had good success with Avery products. Will buy more if needed.The labels are not made for someone who needs each label to say something different. I don’t need 10 stickers to say the word storage, or anything else 10 times. And also the stick on labels are bigger than the tab they’re supposed to stick to. I had to hand write very small and cut labels in order for them to stick on the tabs. However, I was able to turn around and label my home canning jars with the tiny printable labels since it will print the same word or words 10 times. The concept of a sheet protector with tab is what I needed for a work project. But I needed six packs of eight dividers and I need it every label to say something different. I found it wasteful to have a sheet full of labels for the tabs that I could not really customize with a printer. I’ll buy the product again, because I haven’t found any other like it.The reason for a lower over all is the label itself. It is a stick on label & not an insert one. Also a little bigger than the tab so it sticks to the page before.These make my job so much easier!!! Love themLabel template available online but no instructions for how to apply labels to tab and since they don't fit exactly the same size as the tab, we had difficulty. When place over top to have tab on both sides, back half came "unglued." The same thing happened when we applied them on one side of tab with bottom of sticker placed on the sheet protector where tab is attached (the sticker wouldn't stay on the sheet protector, caught the edge of the page before it and loosened and or removed the sticker from the tab. We ended up having to cut off part of the sticker after they were attached. There were no instructions on the website either. Whether a defect in that the sticker size doesn't fit tab, I'm not sure though it seems the most plausible, or it could have been us.The positive: Great quality, durable. Having tabs on the sheet protectors is great because it means you can put pages in regular sheet protectors between this product and tab sticks out far enough to see it without getting hidden by all the pages like a regular divider would.Purchased these for my teacher binder. I love that I can print nice section dividers but still see what the sections are when it's closed. The one thing I did not like was the printable tabs. They are clear and I went to the (Emery?) website to format and print and they can out wth tiny printing and off center even though that's not how they looked online. I ended up using a vis a vis markers to label the tabs. This way it dries but I can later remove with water and re-do. Overall, I would recommend them.The final product is useful and looks very nice. However, after I first applied them, even though the bottom of the labels were at the very bottom of the tab, the top of the labels went up too high and would stick to the other tabs and labels as I turned the pages, and start coming off a bit. I had to remove them and cut them down quite a bit so they fit properly. This is annoying, made the final product look less professional, and for this price they shouldn't have this problem.Worked perfect for me. Just as shown! Great labels tooOn time, as promised, undamaged in shipping. good value for the moneyThese are totally over priced. Staples sells for $ 8.00.
