I absolutely love these glass storage containers! They feel very well made, quite durable. They are microwave/dishwasher safe, so they do clean up with ease even when washing by hand. I love the green colored snap on lids, they are strong & the perfect thickness as they do not feel flimsy. The only reason I took one star off my review is that some of them do not stack well due to being similar/different sizes that will not fit into each other. Otherwise this set is a great value!
