After having cancer, I was told that I couldn't use plastic containers, I decided that I will use PYREX. I had already being using the traditional baking ware. As I look in the internet I found this site. Pyrexware.com i got in there and shopped to my hearts content. I have them in all sizes and shapes, lots of them, I could only be generous buying because of the great prices and specials they have... The name of Pyrex represents an exemplary quality. They're my favorite containers so far!! I don't use any other brand..
