  • Rated 5 out of 5 by from I love these storage containers ! My bad ( as they say ) that I don’t often write reviews yet rely on them when buying items. I bought 2 sets in October and they are just wonderful. I am trying to cut down on using disposable plastic bags, bottles, wrap etc. and also prefer using glass for food storage. These fit the bill perfectly! Once I realized that I should make sure the glass container and the lid should be lined up (and it does help to snap opposing sides at the same time) they are so easy to seal. They are very tight and well fitting. The plastic lid doesn’t really touch the food so it’s ok for me. I have had other glass storage containers but these are by far the best for me. I even use the 4 ounce rectangular one to store 2 sticks of butter on the counter at room temperature. It works perfectly for me. Good bye badly functioning butter keeper.The different sizes and shapes make finding the right storage solution easy.

    Rated 1 out of 5 by from Poor quality The lids warp and will not snap down on all sides after use.

    Rated 3 out of 5 by from Good quality plastic containers. Alas, not glass! These are good quality PBA free plastic containers. My error was reading the description in the summary instead of the title of the product. I thought I had ordered glass storage containers. I will use them but am disappointed they are not glass.
