Usage Instructions

For best results, before use, pre-fill for about 3 minutes, using hot water for hot food or cold water for chilled food (DO NOT overfill your flask). Leave sufficient space in the neck to fit the lid. The top of the flask is wider than most liquid flasks, therefore you should heat your food to the maximum temperature possible in order 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.

Care Instructions

Clean with warm water and washing-up liquid prior to initial use and after every use. DO NOT immerse in water. Dry thoroughly after leaving it to drain. Always store vessel with lid removed.

This product must NOT be used for keeping milk products or baby food warm or cool. Don’t keep perishable foods for a prolonged period. Keep out of reach of children when product contains hot liquids. Before screwing down the lid, please make sure that the sealing ring is undamaged and fully fits into its pocket. Transport upright. Hot liquids can cause scalding.

Not microwave or dishwasher safe.
