Hot food tastes better. If there is one thing that we all can agree upon, then it has to be this. Everybody loves hot food, but we cannot keep food hot for too long. Or is it? After the invention of an insulated Lunch box, keeping food hot became possible. Over the years insulation went through improvements and today we have boxes that can keep food hot for hours. Homepuff has developed a lunch box so superior in quality that it is capable of keeping food warm for up to 6 hours.
