Most burglars spend less than six minutes inside a victim's home and only have time to check the most obvious places for valuables. With this product you can hide your valuables in what looks like an ordinary working closet light- the last place a thief would think to look. This safe has a unique twist lock that locks the top and bottom of the safe together. The closet light is 8 inches in diameter and 3 inches thick. The inside dimensions of the safe are 7 and five-eight inches x 7 and five eight inches x 1 and one-half inches and is divided into 2 shelves. The closet light is a real light and requires three AA batteries that are not included.
