BEOLA 450ml Food Jar Lunch Box Thermos Stainless Steel Double Wall Insulated Travel Food Flask for Kids and Adults, 15oz (Ice Blue)

Purchased one of these for my wife's lunch to keep yogurt cool and fresh. She LOVES it and it worked so well, we purchased 4 more for meal prep and to have everything ready for the week. We now make all items for the jars for the week, leave uncovered in the fridge for an hour to help the inside cool, then put the lids on and keep in the fridge so she can just grab and go in the morning. The items inside (yogurt, fruits, etc.) stay cool and fresh all day long. These have been excellent for their ability to keep food safe from both temperature and spills since they seal so well too. This is one of those products that makes us happy on multiple levels! Good value for the cost vs quality, and sustainable since not using plastic jars or breakable glass ones. We have since purchased other BEOLA products and are delighted with the quality of those too.

Good quality, keeps heat for a long time

I put boiling water in the thermos and checked after around 7 h. The water was warm. So the thermos does what it suppose to. However there is only one lid and some heat is going out from inside (another thermos that I used had a screw lid first and then normal lid), keeping the lid warm.

As long as you pre-warm the flask with hot water for 10/15 mins, and the food you put inside the container is piping hot. The flask will do its job of retaining the heat in your food.

Freshness Sealed - A perfect thermos found to put hot food and cold salads and all the freshness and temperature keep intact. Doesn't spill.Well built and nice/simple design too.

After a few hours the hot food was inside, a vacuum was create and you were not able to open the jar without sticking something to release the vacuum.

Very good and it is made from stainless steel but the top cover let the temperature escape if you touch it after 30 minutes
