The little picnic bags from the Belgian brand Lilliputiens are ideal for school but also for excursions and meals outside.

They are isothermal which allows to keep the food fresh longer.
It has a small handle with a clip (not in the middle so as not to be uncomfortable for little hands) that allows you to attach it to a backpack or schoolbag but also a long adjustable handle to wear it around the body or on the shoulder.
A small pocket at the back of the bag allows you to store a towel, a cookie, or a small flat food that does not need to stay cool.
