Rating : - Disappointed in Amazon's Packing
I had to return them because one of the bowls was SHATTERED. Amazon should do a better job of packing glass items. I will probably not purchase any glass items again from Amazon. I have since bought the pyrex
bowls in town and I like them except that they get extremely hot when used in the microwave. Make sure you use hot pads. The covers fit tightly and they stack well in the refrigerator.
