Know before you buy
The Zojirushi Stainless Steel Food Jar utilizes vacuum insulation technology to maintain optimal temperatures for several hours. While exact duration depends on the initial temperature of the food and how often the jar is opened, it is designed to keep your lunch warm or your snacks chilled throughout a standard workday.
No, this model is not leak-proof. It is designed with a screw-top closure, so it should be kept in an upright position during transport to prevent any potential spills.
No, this product is not dishwasher safe. To maintain the integrity of the vacuum insulation and the finish, we recommend hand-washing the jar with mild dish soap and a soft sponge.
The wide mouth opening makes it significantly easier to fill the jar with chunky soups, stews, or pasta without making a mess. It also allows for easier cleaning and makes it more comfortable to eat directly from the container.
The 10 oz. size is ideal for smaller portions, snacks, or sides, while the 18 oz. size is better suited for a full-sized lunch or heartier meals. Consider your typical portion sizes and the type of food you plan to pack most frequently.
