Ultra versatile- don't limit the bags to purely culinary uses, use them to store makeup, first-aid supplies, pens, toiletries, and much more. The best materials- durably constructed from 100% food-grade silicone with no chemicals, glues, or adhesives, materials exceed us food-grade standards and are dishwasher, microwave, and freezer safe. Design details- bags are made from one piece of silicone and have curved edges no sharp corners so you won't get any pesky, moldy buildup, plus, you can flip the bag inside out to clean if you prefer to hand wash.
