Can recommend the doses of Lock + Lock unrestricted. The lid lock tightly, the cans are both microwave and dishwasher safe. Even after almost a year now use you notice any wear and tear etc. The build quality is very good. The built-in lids seal (which by the way you should take out from time to time for cleaning) they close really very good. With nothing has yet been ausgeronnen etc. So really one hundred percent proof. Another positive feature is that the doses assume no odor and no color. Strong buy recommendation.
