loose enough to move around. They come filled with a sort of cotton foam that will keep lighter items in place.

I usually pack them with plaques that fill up each display as best as possible so they can be stored on end without moving around everything inside.

I dont use any sort of moisture control as they are not sealed tightly but I assume it wouldnt hurt.

The biggest problem is choosing what side to display as many of the plaques have great designs on both sides.

I will find some pictures in the next few days and post them for you to see.
