Storing soups and stews just got easier. Twist 'n Loc container lids twist on like a jar lid and have a leak-resistant seal - so you never need worry about messy spills again. Perfect for soups and stews, flour and coffee. Wide rim, finger grips, and a ridged lid make handling easy. Safe for microwave - unscrew lid before microwaving, freezing, and automatic dishwashing - place in top rack. Measurement lines on containers for exact portion size. Wash before using. Container may become hot during microwaving. Handle with care. Allow container to cool before screwing the lid onto the container. Do not use in conventional oven, under browning elements, or on stovetop. Pack contains round containers with lids.
