UK standard delivery

Enjoy free standard delivery on orders above £50, this option usually requires 2-3 working days. If your order is under £50, this delivery option is available for £3.99.

Next working day

For when you need our products urgently, we offer next working day shipping for £5.99. For orders placed before 12.00, we will ship it the same day to ensure you receive your order the next working day.

Returns

If for any reason you are not satisfied with your order, we provide free 365-day UK returns for all our customers. To initiate your return, simply contact us at team@healf.com, and we'll send you a return slip and help arrange a collection. The item you return must be sent in the same condition as received and inside the original packaging. Once received, we will notify you via email.

For international returns, we unfortunately do not cover the cost. However, we work with an array of carriers and can offer self-posting returns for customers shopping from outside the UK.

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.

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.

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.

NOT microwave safe.
Dishwasher safe but handwash the pot and lid.
