Concealing objects in a book

Another type of concealment is the hiding of messages in the text or on a book's pages by printing in code – a form of steganography.

Prices can vary based on the cost of materials, additional features, and resources used to create the functionality and aesthetics of the hollow book.

The main functional purpose aims for the containment of valuables, memorable items, or contraband within the cloak of an ordinary book.

The scale of gadgetry used to create the seal of a hollow book's closing properties have ranged from simple to complex.

Structures made from real books are sealed and pressed before hollowing the inside pages with a sharp cutting utility.
