I used the combs to combine a photo album and a calendar which I made for gifts. The pages have been opened by several people and the combs are not showing any signs of distress. That tells me that Staples has a good product and I have purchase a larger size to make other projects. I would recommend this to anyone who is interested in combining their projects. It works well with card stock glossy paper and the plastic covers. I used the plastic covers with the glossy covers to bind a fifty two page photo album it worked great!
This product was used to make church cookbooks for our 150 anniversary. I have also used the same product different size to make family calendars. As I said above a great product and I will keep on buying.
We used this for our Charge Conference Booklet. It added to the apparence of the booklet. It also made it look very professonal versus paper clipping or stappling the booklet together. Holds much better using this product.
I have been using these plastic spines for more than 8 years and have not had any problems with cracking or splitting. I have even reused spines more than once and they still function properly.
