A 4-box bundle of plastic food storage bags, the twist tie type. I far prefer them over the zip-lock style for most fresh produce storage in the refrigerator. They are getting hard to find in supermarkets now for some reason: popular preference, I suppose? I must be out of sync... well, to each his own but I didn't want to run out of what I like and then not even find them in the market. Anyway this order should last me for a couple years at least!
