Being a fan of Pyrex products, I was looking forward to using the FreshLock Plus Glass Storage with Microban. The set looks great right off the bat. I prefer these over the plastic ones that aren't designed to be heated. It keeps my leftovers warm enough to be enjoyed a little later, or maintain the freshness once they're in the fridge. They're the food containers I am glad to show to people. I think they're as aesthetic as they are functional.
