I was getting really fed up with the "normal" packed lunch cases/boxes, as they never seemed to fit much in .... So I will tell you what I can easily fit in ....
1 tupperware box with sandwich in,
2 bottles of juice (330ml each bottle.. which I think is the same size of a can of coke)
Box with fruit
I have just bought a Thermos flask (wide neck one, so I can put soup in) and this fits in easily with sandwhich and bottle of juice and crisps/youhurts etc.
My daughter does a lot of activities after schooll, so I like her to have a really good lunch, and have extra in there for snacks after school.
It looks great, it's well made and sturdy. I cannot recommend it more, so I will be buying another 2 for my nieces.
