I know that whatever I store in the Ziploc bag will stay safe until I need it! I am old enough to remember the days before the introduction of secure Ziploc closures. Those were the days of inevitable leaks and messes to clean up ( often accompanied by questionable language)
This is to go to Ziploc size for candies chips other things around the house. With three kids there's constantly use. It's also good for other items around the house And not just food
