Three round silicone food storage bowls in graduated sizes cover everything from dips to dinner leftovers, holding 13.5, 27, and 33.8 fluid ounces (about 400 ml, 800 ml, and 1 liter). The deep round basin suits soups, sauces, yogurt, and grains, with no square corners to scrub. Each container collapses to about 1.2 to 1.4 inches tall when empty, less than half its full height, then pops back to full depth in seconds. Leakproof snap lock lids with an airtight valve seal keep soups, sauces, and dressings sealed in the refrigerator or a lunch bag. The food grade silicone bodies handle minus 4 to 248 degrees Fahrenheit (minus 20 to 120 degrees Celsius), going from freezer to microwave (lid off or valve open) to the top rack of the dishwasher. The BPA free sage build resists odors and stains. Includes 3 containers and 3 lids.
