I'm using these to help organize my tax documents and I couldn't be happier. very well constructed - flexible enough to fit in a 3 ring binder but rigid enough to protect documents.
These are light years above all the dividers made of paper. Have used them before--they never wear out. The heavier weight is especially helpful when you are using the dividers to separate categories that consist of pages kept in plastic sheet protectors.
These dividers are an excellent choice for organizing folders. They have a coating on each tab so it is easy to remove the old tab label and replace a new one. The dividers are clear plastic so you can see the first page of that section a big plus and a time savor and because they are plastic they won't tear as easily. Definitely the right choice. They come in a 5 pk which I like because the tabs are wider and more room to write. The more dividers per pack to narrower the tabs so if you need room to write go with the smaller packs.
