I had a large number of notebooks from various conferences I had been to and they were all on a bookshelf with no way to tell which was which so I could just pull out the one that I needed. Now that I have these Binder Labels, I can go straight to the one that's important right now and not waste my time searching for it.
Trying to do Spring Cleaning in my office, it really helps if I don't have to pick up the same folder over and over again because it's not labeled and so I don't know what's in it. These do the trick, especially with the notebooks. They slip right in!
I needed to organize a large amount of folders I have in a bookcase and this told me that if I labeled them I would be able to go directly to the one I needed immediately. They work! And since they slip into the sleeve, you don't have to worry about adhesive eventually wearing off.
