These are so easy to use, so easy to design, but sadly the adhesive has failed for us, some after a couple of days, some after a couple of months. I glued the tabs back together and onto the divider pages manually a couple of times, but since the tabs themselves are plastic, they were resistant to gluing, too! It was actually kind of embarrassing because our client had to call us to come get our completeled projects back and re-tab them; he had tabs all over the floor by his bookcase! I think the concept for these is great, and I really wish they worked better because I would use them for all our tab needs.
