AIR TIGHT and LEAK-RESISTANT: Stretch and Fresh is the amazing, new food storage container that uses food-grade silicone-lined lids to shut in moisture and eliminate air oxidation, sealing in freshness and allowing for food to last longer than the traditional plastic cling-wrap and other standard food storage containers. What’s more, the Stretch and Fresh also resists leaking. Store soup, or sauces for later uses without completely messing up your refrigerator with spills and leaks!
