My intention is to use all of it's functions. The glass containers are sturdy, and just the right size for my needs. The second-largest container in the set arrived with it's plastic cover chipped away on one long edge.
the lids barely stayed on, they even shifted around they were so loose. this is very impractical for stroing food in the fridge or to go. these are very pretty, and the nesting component is great. however, the function was not there so I returned them. returns were very easy and friendly and seamless.
I always need glass storage for food prepared in advance or left over. I also wind up sending food home with my children in glass storage. I'm giving a set of these to each of my children. They take up very little space in the fridge or cabinet. And they are attractive.
