I love these glass containers. The glass is thick and is BPA free. These are such a great alternative to plastic containers. You can easily store food and then reheat it if needed. The smart seal on the lids snap close tightly and 
securely so your food won’t spoil. The negative about this product is difficult to close. If you have arthritis in your hands or  are a senior you may have a difficult time snapping the lids down. The containers are stackable which keeps them tidy and organized and are dishwasher safe. And the rubber gasket is removable so cleaning is a breeze.
