It is not that difficult to open and the inside space is very limited, but still it is cute on your shelf or desk for a display item and also you can hide something important to you in it. 

    

    It slightly moves as you touch the head of whale by hand and you will notice that the tail also moves a little. As you open the box, you will know why they move and the mechanism of the box is very amusing!

   This box is also very limited production.
