The high quality vacuum stainless steel will keep your food piping hot for up to 6 hours or cold for up to 8 hours.

Made from 20% natural wood fibre, the ergonomic spoon fits snuggly against the body, secured by an elastic and machine-washable strap.

A stainless steel surface on the underside of the lid ensures that food is not coming into direct contact with any plastic.

The compact pod-like shape is compact, modern and minimal. The volume it holds is good for both adults and children. The brushed stainless steel is complemented by the woven textile strap that neatly holds the natural wood fibre ladle spoon securely to the body. It is nice in design if you can take international influence and the spoon form is inspired by Japanese ramen soup ladles (mokusei otama-jakushi). The long handle allows you to reach the bottom of the container with ease, providing a better eating experience. We love this design because it is simple, practical, and timeless in terms of form and function. It might take the odd scratch or dent over time, but this will only add to its character and charm.

How does it work?
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.

How do I look after my FOOD FLASK?
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 the 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.

How do I clean my FOOD FLASK?
Clean with warm water, a sponge 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 with the lid removed.

How do I remove stains?
Fill with hot water, add one teaspoon of bicarbonate of soda (DO NOT put lid on while using this cleaning method). For best results soak overnight. Always rinse before reuse. To avoid stains and residue, wash with a solution of vinegar and water.

Is the FOOD FLASK microwave safe?
No, it is made from stainless steel and is not microwave safe.

Is the FOOD FLASK dishwasher safe?
The ladle is dishwasher safe, but we advise hand wash only for the pot and lid .

How do I prevent vacuum forming in my Food Flask?
If you have removed the silicone seal for cleaning, please ensure it is replaced correctly on the lid. There should be no colour visible next to the central steel circular panel.

What happens if a vacuum forms and I can't open the lid? 
Wait till the food has cooled down (maximum of 6 hours) before attempting to unscrew the lid. Do not attempt to forcefully unscrew the lid to break the vacuum as this can break the lid and could cause hot food to spill out. Always use caution with hot food. To avoid vacuum forming again, check that the lid seal is clean and located evenly within the lid channel.
