Great for creating new categories on the fly. I direct a summer camp and often have to create new sections as the camp progresses. I can write on the tab with whatever pen or pencil I have at hand
I would recommend this product to everyone. The price was exceptional and I would order these again. I made 40 phone and address books for all the mothers in our church for Mother's Day and these dividers were very handy in making each one more organized. I had a lot of comments on how nice the address books turned out.
