The best thing about this diversion safe is that you can literally leave it anywhere and it will most likely be ignored. I mean, it’s a hair brush! A burglar is unlikely to stop what he is doing to brush his hair.
This can be left out in the open in your home, car or even on a boat. It will blend in with any room especially a bedroom or a bathroom. I think it would be pretty safe to hide this in plain sight because no one would ever suspect this hair brush could contain a hidden stash of cash.
