Combo lock book safe keeps it safely hidden in plain sight! Did you know most burglars spend less than 6 minutes inside a victim's home? Meaning they only have time to check the most obvious spots for valuables. Outsmart the thieves by hiding your goods in "plain sight" by using this book safe that looks like any common book that blends in on a bookshelf and is easily overlooked. In addition, the book safe has a built-in steel box (with a 2.75" x 8" x 9.5" inside compartment) with a 3-digit combination lock. That's large enough for many types of valuables and also handy if you wish to lock up your handguns--keeping them away from thieves and children.
