This is *not* a very good method of protecting fragile items. The foam is rather hard and if a package is dropped, it does not dampen the impact much. The result is a lot of *acceleration* which could damage fragile items. *Large bubbles* is the best protection because it does not shift like plastic peanuts sometimes do, and items surrounded with bubbles can actually move inside packages, effectively reducing shocks and vibrations. I had some items delivered to me in the past with peanuts all drifted to one side of the box.
