Why we love it

Large 520ml capacity for meals.
Keeps food hot or cold.
Leakproof design for no mess.

Main Highlights

Upgraded 520ml Capacity Soup Flask: Polar Gear's thermal food container now offers a larger 520ml capacity, providing more space for your favourite hot or cold meals, perfect for longer trips or more satisfying portions, ensuring you stay nourished and energized throughout the day.
Up To 6 Hours Hot Or Cold: Our insulated food container ensures food stays piping hot for up to 6 hours - perfect for hot pot recipes. For best results, simply pre-heat the thermal food flask before use by adding hot water 5 minutes before use. Need your food to stay nice and cold? Pre-cool with ice-cold water - it'll stay cool up to 6 hours. Just pour out the hot or cold water and the double-layered stainless steel will do the rest, so your food or drink stays the perfect temperature.
Zero Spills, Leaks Or Condensation: Thanks to the extra thick double-walled insulation, forget condensation, heat transfer or sweating of your food on the outside of your insulated food jars. Your insulated food flask will stay at room temperature on the outside and the perfect temp inside, so no burning or freezing your fingers when holding. The vacuum flasks also have a leakproof screw lid so as long as it’s closed properly, no matter how bumpy the road is, there’ll be no sticky mess or stains!
Soup Made Simple: No more losing cutlery from home, our compact soup container comes with a durable PP spoon which is cleverly held by the silicone band around the hot food containers. If you don’t need the spoon, the hot food lunch box has an extra wide mouth so you can sip away without making a mess. The non-slip silicone band also allows for easy opening and extra grip, so forget spilling food or drink when on the go!
Economical 2-In-1 Flask For Hot & Cold Food Or Drinks: Whether you want food or drink on the go, our thermal lunch box for hot food does it all, eliminating the need for several drink and food containers as well as reducing single-use plastic packaging. Help the environment by saying no to one-use plastics and go for reusable multi-purpose items like our 304-grade, food and drink-safe hot lunch box. Helping the planet has never been so easy… or so sleek!
Hand wash only, not dishwasher safe. Contents will remain very hot, take extra care if consuming hot food directly from the flask.
