Lock your secret notes, precious treasures, or other personal items inside the Book of Secrets from Ugears and keep them safe from curious eyes. This beautiful 3D wooden puzzle is a steampunk combination-lock box, styled as a book, has a secret compartment, a multi-step opening sequence, and fascinating mechanical action. Your Book of Secrets opens by entering a three-digit combination on the book's spine to release the secret key. Insert the key in the special slot and turn counterclockwise to engage the opening mechanism, then turn the gears counterclockwise to finally open the book. Various windows on the box tell you whether you have completed each step correctly. This secret 3D mechanical box with its complex opening sequence has many mysteries and is both a fun way to store your things and a fun game to play with friends or family as you challenge them to discover the Book of Secret's hidden features.
Books have been used to hide items, in real life and in fiction, for almost as long as there have been books. Homeowners can conceal valuables from burglars by hollowing out a book and placing it on a bookshelf with other tomes. The secret book is easily found by the homeowner, but nearly impossible to find for the crook. In "The Matrix," Neo hides computer discs and cash inside a book, and who can forget the prison breakout in "Shawshank Redemption," accomplished using a rock hammer concealed in a Bible, the pages cut out starting at "Exodus." You can set any three-digit combination you want on your Ugears Book of Secrets by removing the pin block inside the secret compartment. Turn the dials to the combination you want and reinsert the pin block. The key release mechanism will now work with the combination you have set. When you press the lever under the bottom of the book's spine the key will pop out of its slot at the top of the spine. The lever will not eject the key if the three tumblers are set to any other number sequence. You can reset the three-digit combination any time you like by following the same sequence - open the 3D wooden box, remove the pin block, reset the combination, reinsert the pin block, and the key release mechanism is now set to the new combination.
Did you forget the combination? Don't worry, our designers and engineers have you covered. There are two different ways to access the contents of the box without the combination. You can open the Book of Secrets by simply prising off the back panel— insert a flat tool like a screwdriver or metal ruler into the slot between the back panel and the box, then gently jimmy the panel in several places to lift and remove the panel, giving you access to the box. You can also play safe cracker, discovering the combination through touch. Press the key release lever with your finger, holding it in with slight pressure, then rotate each tumbler sequentially. You'll feel that the correct number on each tumbler turns slightly tighter than the others, and that the lever slightly shifts under your finger as the correct number clicks into place. When the last drum is set to the correct number the indicator on the spine changes from closed to open—the key release is now engaged.
