Of course, I did not expect that I could put jewelry, coins, and anything else that makes noise inside, because anyone who touches it will immediately realize that there is something inside. However, the issue is that it is also semi-transparent and it is visible if you have put something inside, for example, banknotes. This can be solved if you put a white piece of paper touching the inner walls, otherwise, it doesn't make sense to use it in general. Nice idea, but they ruined it in the execution.
