Care Instructions

  • Hand wash with warm soapy water and leave it to drain-off.
  • Not freezer and microwave safe.

Tip: Our food jar keeps food warm for up to 6 hours, but the density of the food and usage of the jar may affect the warmth. Less dense foods, such as soups and saucy pasta, tend to stay warmer longer than denser foods. To maximize the jar's performance, it's crucial to follow the instructions carefully, which include heating the jar with boiling water for 5 minutes before adding boiling hot food to it. Avoid opening the jar before consuming the food, as this can cool it down faster.

I like the item because of its size - I have other thermos food flasks but they’re taller so when I put food in it, it all ends up on top of each other. This one keeps the food more level. However, I don’t think it keeps food as warm as my original thermos food flask. It’s also tricky to wash as you have multiple parts to pull apart and it’s not always easy to put it back together again. Overall it’s ok but it’s a shame it doesn’t work as well as it should. I’d still recommend it if the food didn’t need to be kept warm for too long of a period.

The jar does not hold the temperature of the food. The seal does not stay in place. When I complained about the quality of the product I received a reply after a week with a user manual, which I find very offensive.

Bought it for my husband

I bought it for my husband. The thermos can hold quite a lot and the seperator inside is a good idea

Good quality

Very good quality, however foods are mildly warm after 4 hours. Come lunchtime it's okay. Double cap is good avoids any leaks. The divider and the handle are a bonus
