I have been using these binders for approximately 10 years. I make a family calendar for my siblings and extended family that wishes a copy. This product was also used to make the 125th anniversary cook book for our church's anniversary celebration. We sold these cook books all year long at the various celebrations that we had to celebrate the anniversary. We got many a complement. We also like the idea that if we decided to expand the cook book and had any left that we could unbind and rebind with the same binder to add additional pages.
I have been using these binders to make family calendars since 2003. The number of calendars has increased over the years and everyone likes how they are put together. We also used this product to bind our cook books that we make to sell for our 125th anniversary at our church. We had gotten quite a few complements on how well they were constructed. They liked the idea that if we wanted to expand the cook book and we had some of the older additions that we could unbind and add the new pages without too much diffuculty.
