To lock in freshness, this square-shaped shallow food-storage container features a lid with four easy-to-open and -close clasps, plus an all-around silicone liner that ensures a 100-percent airtight and leak-proof seal. The unit's 10-ounce capacity works great for storing leftover sauce or a trail-mix snack to take on a day hike, while its durable see-through housing makes it possible to view contents at a glance. Use it to store food items in the refrigerator, freezer, or pantry; to heat food up in the microwave (with lid vented); or to store household items in the bathroom or arts-and-crafts room. Other highlights include a stackable design, temperature resistance from -40 degrees F to 230 degrees F, and the option to clean it by hand or in the dishwasher. The food-storage container measures 4 by 4 by 2 inches and carries a 30-year limited warranty.
