This Thunderbirds lunch bag is perfect for work, school and long sessions in the lab! The cotton bag features a classic image of Brains on the front, as well as the words, "Brain food" against a grey background. The side lining of the bag is coloured blue, and includes a repeated formula pattern, while the back has another, "Brain food" design to really let everybody know that this is a lunch for geniuses only. Not only is the lunch bag insulated to keep food cool, it also benefits from a toggle fastening and a PU carry handle. A great option for anybody who needs to keep their grey matter fuelled for excellence all day long.
