Abstract: An EVA book comprises a number of leaves and at least one pivot member. Each leaf has an edge and at least one hole adjacent to the edge. A slit extends from the edge into the hole. The pivot member includes a central member and two outer members respectively provided on two sides of the central member, thereby defining two outwardly facing recesses. Each leaf and the pivot member are deformable to allow forcible insertion of the pivot member into the hole until the central member is received in the slit, thereby allowing relative pivotal movement between the pivot member and the leaves. In addition, each leaf and the pivot member are also deformable to allow forcible removal of the pivot member from the hole.
