What is the best way to use the thermoses?
For best results, pre-fill with hot water for hot food, or cold water for chilled food, for about 5 minutes and empty before you use it (DO NOT overfill your flask). Leave sufficient space at the top to fit the lid. The top of the flask is wider than most liquid flasks, therefore you can heat your food to the maximum temperature possible to have optimal heat retention. Lid must be hand-tightened but without extra force as the extreme temperatures will make it more difficult to open your food flask.Are the thermoses and lunchboxes leak-proof?
Our lunchboxes and thermoses are leak-proof, but it's important to ensure that the product is properly sealed. Make sure the edges of the base and the silicone seal on the lid are clean and dry for a secure, airtight seal.What material are thermoses and lunchboxes made of?
