This 25-ounce stainless steel food jar uses vacuum insulation to keep contents hot or cold for hours. The 18/8 stainless steel construction is durable and sanitary. The tight-fitted lid includes a gasket that seals to minimize leaks and maximize heat retention. The 2.5-inch wide opening makes it easy to fill, clean, and eat directly from the jar. The compact design maximizes capacity while taking minimal space.
