If you keep stuff in notebooks you need dividers tabs. These are really good quality and hold up well with use. Before we found these we would go through old notebooks and pull out tabs. These are priced so low it does not make sense to go to that expense. Now we buy new tabs leave the old in the books and everyone is happy. The paper is just the right thickness the inserts are easy to use the multicolor is very handy and the pages are reinforced and do not pull out of the books. These are a great value.
