Query: Small but serves it's purpose

The rock I received actually is pretty small, a little smaller than the size of my palm. It has a flat bottom with a piece of plastic and a little door you open to place an object inside. This area is pretty small so don't plan to hid much more than the key. The rock I received was grey/black and didn't look that much like the picture in shape. I used it as a prop for a spy birthday party where I hid a clue. I did place it outside in my landscaping and in my opinion it was pretty obvious that it didn't look like the other rocks. I'm not sure I'd use it to hide something of importance. But for the price it did a good job.
