Floor safe

The important thing to remember is that Safes can be attacked and broken open with the right kind of damage. Acid will eventually eat through it and a tough guy might just have the weapon to bust it open in a few strikes. You can install locks on safes. If the person is smart they will try to bash it open if the lock is good. It might be a good idea to put a keyed lock on your safes because most pickers do not bring potmetal lockpicks, and people tend to rob semi-naked just in case. (As to not give your target in a better position than yourself)
