My mom came across these lunch boxes a couple weeks ago. The only thing I don't like is I wish the lunch box had a cute print on it.
When you buy a lunch box for $8 they come with 4 containers that fit inside the boxes. I have been using it this week & the only thing I've found is that liquids leak out of it, so everything needs to be solid.
