I thought of that. For certain kinds of items (berries to snack on, or nuts for instance) I think I will dig out some of my Ball jars.
I just purchased some glass bowls made by Pyrex. The lids are plastic, but at least the bowls are glass.
I also remembered that we own a couple of stainless steel thermos bottles. I am going to try to use one of those instead of a plastic water bottle to bring water to work. A little unconventional in my work setting, but maybe it will do the trick.
