Water Bottle Diversion Safe
This is one of the most realistic diversion safes ever invented. Most burglars spend less than six minutes inside a victim's home and only have time to check the most obvious places for valuables. This unique safe allows you to hide valuables inside a common bottle of water - one of the last places a thief would think to look. This is an actual water bottle which is about 9 1/2 inches tall. A unique locking mechanism insures that the bottle will not accidentally open. When the base of the bottle is rotated counter clockwise and pulled apart a hidden area that measures 2 1/2 inches by 2 1/2 inches will be revealed. This is plenty of space to securely hide your cash, keys, jewelry, credit cards, etc. The bottom portion of the bottle below the label comes filled with water. The hidden area is behind the label. To reduced the weight when shipped, the top portion above the label is not filled with water. You can unscrew the cap and fill it with as much water as you would like.
