Very nice case! There is a thinner foam in the bottom, and a huge foam slab in the middle, what is pre-cut into an approx 10x10 mm grid. The cut is not very straight, but ok. The round knob under the handle is a screw, what goes into a copper threaded insert, what is a hole into the case. The screw has a rubber O ring under it, for sealing.
