Bring along your valuables while you bring along your favorite beverage in these water bottles that have a secret hidden storage compartment. Made of stainless steel, these 3.15" x 12.2" vessels have a classic soda bottle design with a secure cap and a flared bottom. Unscrew the bottom compartment to reveal a space to put keys, cash, cards and other valuables that can hide out in plain sight. A great idea for the beach or pool, or use it as a "safe" at home. Keep an eye on your stuff while you quench your thirst. Natural silver metal color. Add your organizational or company logo or message to customize.
