I keep the boxes folded up in rubbermaid containers in the garage. I nopw have 5 containers holding over 300 boxes. I do not keep the styrofoam or peanuts because I don't plan on selling any pieces. If I did, and offered my Coquille for sale(without the original peanuts) or my Erie Land Light(without the original styrofoam), I could get the same price either way and don't have to put up with the problems of the styrofoam. It is totally up to the collector as far as I'm concerned whether to save the styrofoam or not.
