Abstract: A fastener including a screw receiving element extending along a first axis and having a first end and a second end, the screw receiving element including a through hole extending through a thickness of the screw receiving element perpendicular to the first axis, the fastener further including a retention element arranged at the first end of the screw receiving element, wherein the retention element is plate-shaped and extends in a direction perpendicular to the first axis of the screw receiving element, and the retention element further includes a panel facing surface extending in a plane substantially perpendicular to the first axis of the screw receiving element, and side surfaces extending in planes substantially along the first axis of the screw receiving element.

Abstract: There is disclosed a book with a front cover formed by a front base layer and a front decorative layer. The front base layer has a first front face portion, a second front face portion, and a front free edge. The front decorative layer is disposed on the second front face portion. The book has a rear cover formed by a rear base layer and a rear free edge. A binding layer extends across the rear base layer and along the first face portion of the front base layer cover. The binding layer is adhered with the rear base layer and the first face portion so that the front decorative layer extends from the front free edge and across the second front face portion. An edge of the binding layer abuts an edge of the front decorative layer. This arrangement eliminates a free edge between along the front cover of the book. The book includes one or more pages disposed between the front and rear covers. The pages each include respective page base layers and each base layer including a page binding edge.
