I had to produce 10 identical notebooks for a client and was agonizing over how to do that efficiently and professionally. These tabs worked perfectly. I was able to customize a nice index sheet for the front with some details. The tabs were then created by printing a single sheet and inserting into a special plastic page that even accommodates larger binders. I got very professional looking tabs without the time it takes to cut and insert in regular ones, which, with 10 binders, would have been incredibly inefficient. The Wilson-Jones website provides downloadable templates that make it all a breeze. Very well designed product.
