I bought this for my 9yr old Son. He opened this as a present to him from me on Christmas. He loved it. The inside of the Lunchbox had a hard case in it. Which I believe keeps the shape of the Lunchbox and most importantly safe temperature of the food put in it. So if it is to be cold and left in the refrigerator a decent amount of hrs the food should stay cold for a while, and vice versa if hot. My Son will be starting School going back in style.
Thanks Nike
