I tried the bags first (purchased @ Whole Foods), then the boxes from HSN. I have had a much better experience with the boxes than the bags. I still have the boxes and use them for fresh fruit and veggies and I really do think that they extend the fridge life of these items. I use them a lot for celery, berries, cut melon. My younger son loves strawberries, for example, and I'll get a big container of them, wash them, put half away, whole, in a green box, and the other half I'll cut up and put in another green box . Both cut AND whole they've lasted an extra few days in the boxes.
