Product overview
Built 490ml Vacuum Insulated Food Flask Double-Wall Stainless Steel Leakproof Thermos For Hot Cold And Frozen Foods Blue
The Built 490ml Vacuum Insulated Food Flask provides a convenient way to carry hot, chilled or frozen food while maintaining its temperature for several hours. Double-wall vacuum insulation helps keep hot food warm for up to 6 hours, chilled food cool for up to 24 hours and frozen food frozen for up to 4 hours.
Made from durable stainless steel, the flask is designed for everyday use and features a classic navy blue finish with a black silicone sleeve. The sleeve provides additional grip, making the flask comfortable to handle.
The twist-lock lid incorporates a silicone seal to provide a leakproof closure, helping prevent spills when carrying soups, curries, salads, yoghurt or other foods in a bag. Its 490ml capacity makes it suitable for packed lunches, commuting, picnics and days out.
