I have used many different pots for meals of my children (including pots beaba that are really cool but not enormously empillent and take place to store) and I finally found pots that fit easily . There graduations that are very practical, and lid colors are nice. For now they hold well in the dishwasher and the microwave but I barely 1 month of use so I do not know what happens in the long run ... The only disadvantage is that they are a bit stiff so do not use excessive force when they are stacked or they are a little difficult to separate.
