Review on OUERMAMA Professional Playing Restore Tutorial by Jim Acquista

Metal insert, one side of the box is magnetic. On the other hand, you can slide the box to check without the insert falling out due to the magnet. The downside, and that's a big downside. The metal insert makes a strong dull noise when falling. Very audible. This will not fool a 5 year old. The rest is well done, hence 2 stars. I will try to find a suitable plastic insert.
