Here’s an interesting spy gadget I’ve come across online. It’s a safe inside a bolt. I’m sure spy fans will definitely appreciate things like that. In reality, it’s only useful to keep money and other small items.
One thing to think about. If you are carrying a giant bolt with you, while your main job is sales manager, then it could create a suspicion. In such case, maybe you can find some more regular looking safes to carry with you.
