I received a few of these for my bridal shower several years ago, and I still use them a lot! Pyrex makes great quality products and I'm always giving Pyrex for bridal showers because I use them so often!
I have had my pyrex portable for a few years. Keeps hot food hot and cold food cold. The only problem was the zipper broke within the first year of use.
What a wonderful product! I tend to bring lasagna or similar dishes to family gatherings and this is perfect for not only transporting it easily, but keeping it warm as well!!
My sister bought this for me years ago and it is a awesome thing when taking things to family gatherings.
Pyrex Portables are so great. I use mine anytime I am taking a casserole somewhere. You just put in either the cold or hot pack depending on the foods temperature and then your casserole zip it up and go on your way.
