Round containers block out air and lock in freshness to keep your foods fresh for longer. Twist 'n Loc lid twists on like a jar to create a leak-resistant seal and prevent spills. Wide rim, finger grips and a ridged lid make handling easy to help you keep a secure grip when transporting foods. Durable construction can be used in microwaves, freezers and dishwashers. Containers are perfect for storing and transporting messy foods like soup, pasta, cereal and more.
