Upgrade your OmieBox UP with the Omie Stainless Steel Flask Container — the perfect way to keep meals warm, fresh, and delicious for hours.

This removable 18/8 stainless steel vacuum-insulated container fits seamlessly inside the OmieBox UP, allowing kids to enjoy hot favourites like pasta, soup, or rice alongside fresh snacks and fruit.
