Does the thermal coating come into contact with the contents or me?

No. There is no coating on the outside you touch or on the inside of the jar. The thermal coating sits on the outer wall of the inner body and consists of a copper layer. Your food only ever touches food-safe 18/8 stainless steel.

How long does food stay hot?

14 hours hot and 19 hours cold, with no preheating. Rinse the jar hot, fill it to the top, and keep it closed until lunch.

Is the lid plastic?

The lid is made from recycled, food-safe plastic. The body your food touches is uncoated 18/8 stainless steel.

Is it tested for lead?

Yes. It is independently tested for lead under the US CPSIA, and we retest every year. You can download the current report on our certificates page. No form, no account. All seals are food-grade silicone, BPA-free.
