Acid-Free Binder s Davey Board, 100 Pt. 15 in. x 20.5 in. (4/Pkg.)

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.
