I have some that are 2-3 inches thick. The ones that came with the wine bottles are 6-7 inches tall. I have a box with 15 full quart jars of tomatoes on it, and it holds up fine.The styrofoam inserts are effective, even that thin?
We're going to build a pantry in the basement, and then I'll have to get rid of the styrofoam. Unfortunately, our recycle center that took it is no longer operating, so I may have to throw it out.
