Psst, listen in: the LEUCHTTURM book safe is the perfect hiding place for your valuables, important documents, cash and jewelry. On the outside, it looks like a LEUCHTTURM stock book, but when you open it up, the inside contains a steel safe with a secure cylinder lock. By assuming the format of book pages, the fore-edge is plastic, the book looks extremely authentic and is completely inconspicuous. As the book size is relatively small, this book safe is ideal for taking on your travels. Material: leatherette cover, safe made of steel (thickness: 0.8 mm). 2 keys, each with a separate key number that is unique to the integrated lock, are included. Book color: black with gold-colored embossing. Size of safe (inside): 229 x 137 x 40 mm (9 x 5 ? x 1 ?"). Size of book: 240 x 155 x 55 mm (9 ½ x 6 ? x 2 ?").
