This portable safe provides some extra heft and security with a customizable four-digit combination. It's also water-resistant!

Promising review: "My family and I travel a lot, and we’re beach people. Mostly on cruises, but every beach we hit, I’m the one keeping an eye on our stuff. We don’t go to bad places, mind you, but I’m always paranoid about things like my phone or wallet getting taken. With this handy safe, it’s simple to store your things AND secure them to a beach umbrella, deck chair, whatever. It’s sturdy, easy to use, and best of all, gives you peace of mind. Now, it’s not huge - we can fit two iPhones in there, or one phone and a small wallet or money clip, but that’s all you really need it for. Don’t hesitate to get this safe, it’s worth it." —Sosai X
