Produce Food Saving Containers w/ Vented Lids

The one thing that would improve these fruit and vegetable storage containers would be some kind of mark or notice that the vent should be open for fruit and closed for vegetables, difficult to remember if I haven't used them for awhile. But one of the biggest benefits is that I feel more confident in buying produce marked down for quick sale because of expiration date. Whenever I buy produce I switch them to these containers as soon as possible and they last usually days longer than if stored in bag from produce market. Especially helpful to me is buying salad greens mix ready to serve. At the high cost of everything nowadays you can quickly recoup the purchase price because it stays. fresh longer - cuts down on waste and saves trips to market to buy more when you discover how much longer they last past expiration date.
