Hide and secure your valuables with The Locking Book Safe. It combines 2 great methods to safeguard your valuables: first, it looks like an ordinary book- the last place a thief would think to look. Place it on a bookshelf and it will blend right in. Second, it has a built-in metal box that can be locked (2 keys are included). The area inside is extremely large- a full 9 inches by 5.5 inches and almost 2 inches deep! There is enough room to hide and secure many items, even some small pistols. For example, the Beretta 84 Cheetah and the Glock 19 are 2 pistols that can fit inside the SWBSK, enabling you to keep your firearm hidden from thieves and secured from children. The book measures 9 and five-eights inches x 6 and five-eight inches x 2 and one-quarter inches on the outside.
