Hinge boxes are constructed from premium high density, acid-free, binders board and are covered in durable grade F library buckram available in a variety of colors. The exterior of the trays are usually covered in the same colored buckram material and the interior is lined with a conservation quality paper. The hinge box is titled directly on the covering material. Boxes are custom made to the dimensions of the volume to be housed. The measurements may be provided by the client or taken from the actual volume at an ECSConservation facility. The hinge box is an economy version of the clamshell product that will meet the basic needs of your collection.
