The Ultra-Seal™ 2.2 Quart Pitcher features a gasket and four latches in the lid that create an airtight and watertight seal to prevent liquids from leaking. This spill-proof lid, along with graduated measure markings on the base, allow for mixing lemonade and other beverages right inside of the pitcher. Designed with a slim profile, the pitcher fits conveniently in the door of a refrigerator to use space more efficiently. Ultra•Seal™ containers are freezer, microwave and dishwasher safe, as well as BPA-free and phthalate-free.
