SAFEGO Portable Lockbox Safe Features on "Look! What We Found" on Good Morning Arizona (KTVK-TV). 

"This is a mini safe. This is awesome. For your phone and your keys, anything else that you want to stash when your jump in the ocean or when you surf. It's called SAFEGO, and you can bring it with you anywhere and attach it to a chair or a fence maybe.

That's good if you put it on a chair - someone would have to walk off with the whole chair.  And guess what, when you're hiding your phone and your wallet in your shoe, everyone knows it's there. That's where everyone puts it." - Good Morning Arizona
