What a great way to keep your valuables safe at the beach…. and it is free at that. You can use any bottle where the top of the container pops off – not the cap but on some bottles the top of the dispenser can be popped off from the bottle. Add a washcloth to wrap money and keys inside the bottle so if someone cam upon it they wouldn’t hear it rattle and nothing inside would move. For an added bonus after you really apply lotion to yourself/family place a little on your hand and dab on the bottle for a great effect. If it looks like lotion and it feels like lotion when a would-be thief decides to steal they more than likely ill drop it and look elsewhere.
