The vacuum-insulated Thermo Pot is cleverly designed to keep food hot for up to six hours. The wide-mouth, cork and polypropylene top keeps it tightly sealed, while the included spoon sticks to the outside magnetically for an all-in-one lunch companion. The 6.7h x 5"diam., 17 fl. oz. Thermo Pot’s vacuum is guaranteed for 10 years. Hand wash only.
