Our item is a foam filled externally and internally. It has an egg carton on the bottom covered by foam. The egg carton give it a spring like feature witch will give me a bounce, at impact, that will help us reduce most impact. Our model will help us by not exploding, because it is compact and strong with tape. Our interior is Styrofoam walls, with the penny boxes put into a corner with foam. Our lens is on a cut out that holds it self with plastic. This is a good design, which weighs 2.41 pounds. And is compact to take all impact.
