lunchbag
you invest a lot of time in creating a nutritious lunch package for your child just to cram it into an ugly plastic bag afterwards. your eiffel tower made of crackers turns into a mushy mess and your child into a hungry beast.
to keep your kid's lunch beautiful inside and out you might want to consider helga.
not a german au-pair, but just as useful - a lunch bag made of felt and designed in berlin.
