This clamshell box has several unique characteristics. For starters, most clamshell boxes we produce are .040 or under in caliper–however this box is made with .080 material which gives it outstanding structural rigidity. You will notice that it is finished with foil stamping in gold along with a gloss film lamination. In addition, there is a cut out in the spine to reveal the copy on the spine of the bible which was achieved by registering the blank to the wrap.
