The NUK containers are very practical and coloring also when filling of dark vegetables (carrots, pumpkin, etc) is not one. You see, even after 3 months of use as the first day. The size may fall a little small. For the first zarghaften food tests are sufficient, but now (my daughter is 7 months old) she always eats at least two containers empty. So in the long run it is unfortunately a little impractical.
