These Dasani Diversion Safe Bottles of Water are one of the best ways to safeguard valuables ever invented. Our diversion safe bottles of water allow you to hide valuables inside -- one of the last places a thief would think to look. This is an actual 24 ounce water bottle which is about 9 1/2" tall. A unique locking mechanism insures that these diversion safe bottles will not accidentally open. When the top part of the bottle is pulled upward a hidden area 1 1/8" tall by 2 3/4" wide will be revealed. The hidden area is behind the label.
