kiwi box inside structure

I think several ways to make this put the fruit bowl in place and they will not move around. The first idea is make tray but it make the box look bulky. Second one is use some sponges, which cut in cuboid shape and stick on piece of cardboard but the fruit bowl still can move so in the end I decide use square cardboard with some ribbon on it to tie the fruit bowl.
