Hailed by America's Test Kitchen as the best food storage containers you can get, the RubberMaid brilliance line has me sold and i'm not looking back. Their wing-clasp design ensures a tight seal with absolutely no leakage of food or smell. They are incredibly temperature reisistant and BPA free so you can microwave them, freeze them, or throw them in the dishwasher with no second thoughts. They are perfect for meal prepping or storing leftovers, and I can't reccomend them enough.
