All Purpose Cleaner Diversion Safe is made from a real All Purpose Cleaner can. The added weight makes the can appear as real, however, it is not a real can of cleaner. The hidden compartment is on the bottom of the can. It closes tight to prevent accidental opening. Unscrew the bottom, place what you want inside and then screw the bottom back on. Perfect for putting under the counter or sink at work, home or college dorm. The inside dimensions of the safe are 1 1/4 inches by 3 3/4 inches.
