Take your favorite foods to-go with the Sterilite Ultra•Seal™ 4.0 Cup Square food storage container. It features a color-coded matching system to help find the correct lid and base combination without rummaging through the cupboards in your home. The gasket and four latches in the lid create an airtight and watertight seal that keeps food fresh and prevents liquids from leaking. A vent in the lid releases steam when the container is placed in the microwave, and all containers store efficiently both when in use and when not in use. Ultra•Seal™ containers are freezer, microwave and dishwasher safe, as well as BPA-free and phthalate-free. The overall assembled dimensions of this item are 6 5/8″ L x 6 5/8″ W x 2 1/2″ H.
