This seems more like a replacement for Styrofoam rather than cardboard boxes, though it could certainly be used in places we already use cardboard inserts. But probably still need a cardboard box on the outside. Thankfully we can grow those too!!

It seems rigid though, more akin to cardboard than soft styrofoam. I don't see anything about how dampening it is, but from the pictures I also assumed it was more like cardboard than styrofoam. Maybe the color is deceiving me though.
