Promising review: “We’ve been using all sizes of Stasher bags for nearly a year — mostly food-related — and have not had any issues with a single one. We use them to keep crackers, chips, and bread from getting stale after opened; to keep leftovers in the fridge or freezer; pack sandwiches, meds, dog food, or treats; and so many more things. We sous vide in them, heat up food in the microwave in them, put them in the dishwasher, and marinate in them. They don’t leak, they don’t smell, are easy to close and open, and don’t take up much room compared to traditional Tupperware or other food storage. If you put squishy stuff or liquid in there, soaking with baking soda and vinegar for 30 minutes can make sure the crevices don’t mold as some reviewers mention. They do cost more than regular plastic baggies and require more work because, obviously, you don’t just use them once — make the switch and stop with the single-use plastics.” —Maison Leach
