Know before you buy
Yes, the two included 20-ounce inner containers are BPA-free and microwave-safe, making it easy to heat up your meal before placing them back into the insulated jar.
The vacuum insulation is designed to keep food hot for up to 10 hours and cold for up to 24 hours. For best results, pre-heat the jar with boiling water for hot food or pre-chill it with ice water for cold food before filling.
The inner containers are dishwasher safe, and we recommend placing them on the top rack. The main stainless steel jar should be hand-washed to preserve the vacuum seal and exterior finish.
Yes, the screw-top lid is designed with a wide enough diameter to serve as a convenient bowl, which is helpful if you are eating on the go and don't want to carry extra dishes.
No, the double-wall stainless steel construction ensures the exterior remains cool to the touch even when the jar is filled with hot food. It is also sweat-proof, so you won't have to worry about condensation when storing cold items.
The total capacity of the jar is 47 ounces. It includes two 20-ounce inner containers, which allow you to pack separate portions or different types of food while keeping them organized.
