I'll be wonderfully cope with the containers. The only shortcoming is that let the partially open lid really difficult. Thaw just after. My husband was recently so desperate because he does not baby milk came to, he had to make a hole in the lid. So we need the right combination of turn and pull the lid to open. shame because the containers would otherwise really are very practical and you can freeze anything in it and thaw. I used them in spite of all very happy and would buy again at any time, since it is ideally suited for traveling!
