Do the math ... 5 bowls plus 5 lids in every size needed equals all your microwave cooking/reheating/storing needs in one perfect set (at one great price!). Lids feature easy-twist vents, releasing steam to prevent sogginess or closing to keep food warm before serving, or seal in freshness for storing in fridge or freezer. Stay-cool, comfort-grip handles make bowls easy to retrieve from microwave, and are designed to allow nesting for easy storage. Top-rack dishwasher- and freezer-safe plastic. Set of 5 bowls with lids range from 8 oz. (4 3/4" long x 3 1/4" wide x 2" high) to 36 oz. (9 1/2" long x 7 1/4" wide x 2 1/2" high).
