I picked up this safe to safely store things in my car. You could use this in a dorm room or an office just as easily as you could your car. If you can wrap the cable around something that is permanently mounted, it won’t disappear without some bolt cutters.
The case is durable enough for short term safe storage. If you are going to store something in this that you want a little more protection for, you will probably want to remove the plastic inserts and put some foam in it instead.
It is very easy to move from car to car, or one location to another. If you are thinking about getting one, then I’d recommend it. It is much better than leaving something valuable just hidden under your seat.
Same safe with a 4 number lock and key:
