Designed according to the characteristics of children’s campus dining, the school lunch tin box for children has a scientifically arranged internal space with a capacity perfectly fitting the storage needs of children’s formal meals, side dishes, fruits, pastries, milk and snacks. The flat interior without dead corners can perfectly hold staple foods such as rice and noodles, as well as meat and vegetable dishes, and flexibly store cut fruits, bread, biscuits, nuts and other supplementary foods, adapting to children’s eating habits of small and frequent meals and diverse diets.
