An ideal choice for people on the go, the 350ml Food Jar with Microwavable Container is built to last and loaded with features to make for a more enjoyable eating experience. Thermos vacuum insulation technology virtually eliminates temperature change within the food container by creating an airless space between two stainless steel walls. The result is an insulation layer that performs any other. A superior insulated container you can depend on to keep your food hotter, colder, fresher, longer. This food jar keeps items hot for 4 hours or cold for 6, making it a great choice for long days where mealtimes might be a little irregular. The Tritan copolyester inner liner is microwave and dishwasher safe. Food can be stored in the 100% leak proof jar either hot or cold. The insert is removable, microwavable and easily locks into the food jar. Constructed with double wall stainless steel, this 350ml food jar is virtually unbreakable, yet its sleek design is both eye-catching and functional. The contoured body shape is easy to grip and the wide mouth opening is easy to fill, eat from and clean. The flip top opens easily with a push button lid. The Food Jar with Microwavable Container features premium, double wall vacuum insulation so the stainless steel body stays cool to the touch with hot items and condensation-free with cold items.
