Acid-Free Binders Davey Board 100pt 15x20 inch 4 Sheet Pack

 A book's cover consists of three boards  the front, the back and the  spine  that protect the contents and provide support to the book.  Strong, acid-free board made by the Davey Company is the choice of  binding professionals. Unlike cheaper laminated chipboard, this dense  single-ply board is very stable and resists warping. The superior  density keeps corners and edges from denting.
